To lighten the load the Apollo atronauts left many things behind on the moon including their PLSS backpacks, helmets, and gloves. Was there a procedure in place for this? How did they accomplish this task? Where can I read up on this?

Of course there was a procedure on this. There was a procedure for everything.Basicly it was (IIRC) - close the door and repressurize the AM
- take of the helmets, gloves, outer boots, PLSS, etc
- store everything that was going back up
- connect to the AM's oxy supply and re-don pressure helmets and inner gloves
- depressurize the AM and open the door
- chuck out everything that wasn't going back up
- close the door and repressurize the AM
- remove helmets, disconnect from the AM's oxy supply

Typically that laundry list is followed by, "If they threw out all that stuff, how did they manage not to suffocate while jettisoning it?"
In case it's not clear from the checklist, the astronauts were hooked up to the spaceship's air supply. You can attach those hoses either to the backpack or to the sockets in the spacecraft. That lets you throw the backpack out.
And most people don't realize that there was an inner and an outer helmet, inner and outer boots, and inner and outer gloves. The inner versions of all that equipment are the ones that actually held the pressure and were locked onto the suits with airtight fasteners. The outer versions were unpressurized and provided only mechanical protection. The gauntlets and overshoes were worn over the inner pressurized versions to protect against the abrasive lunar environment. The outer helmet assembly was worn over the "fishbowl" helmet and wasn't pressurized either -- it just held the visors, etc. in place.

Did NASA monitor their suit pressure from earth? Or was that something that the astronauts would monitor themselves?

They definitely had a pressure read-out and controls on the chest pack, and I'd imagine pressure would be important enough to put on the telemetry too, but I doubt if the ground had a way to control the pressure remotely.
Edit to add: Yes, suit pressure was on the telemetry. In addition to the pressure read-out, there was a low-pressure alarm tone.

In the footage of Apollo's 15 and 16 you can hear both Astronauts giving their readings and then also Huston confirming the readings on occasion. One major one was a problem with Jim Irwin's suit early on during EVA 1 of Apollo 15
From Apollo Lunar Surface Journal:
120:41:34 Allen: We copy, Dave and Jim, and we're standing by for an EMU (Extravehicular Mobility Unit, meaning the suit and backpack and related gear) status check when convenient.
120:41:37 Irwin: (To Dave) Let me know when you're finished...(Stops to listen to Joe) Okay, I'm reading 3.8 (psi) on my gauge. Flags are clear, and I'm reading 75 percent (oxygen remaining).
120:41:57 Allen: Roger.
120:41:58 Scott: Okay, I'm reading 3.85 (psi), flags are clear, and I'm reading 75 percent. (Long Pause)
120:42:29 Irwin: Trying to...Like walk up out of a crater each time. Uh! Boy!
120:42:31 Scott: Can you make it?
120:42:33 Irwin: Yeah, I'll make it. I don't know how it's going to work when I get that geology pallet. Might need a little help there.
120:42:38 Scott: Give a call (if you need help).
120:42:41 Irwin: Okay, I have a flag...(correcting himself) I have a tone, rather.
120:42:48 Scott: I got one (meaning that he, too, heard a tone). I guess I heard yours.
120:42:50 Allen: (Sounding a little concerned) Roger.
120:42:54 Scott: Got any flags, Jim?
120:42:59 Irwin: I can't quite see it. No, I don't have any flags.
120:43:04 Allen: We concur, Jim. No flags. (Pause)
120:43:10 Irwin: Are you finished at the MESA for a little bit, Dave?
120:43:12 Scott: Oh, no. (Finishing with the LCRU) This...
120:43:16 Irwin: Okay, I'm going to...
120:43:20 Scott: ...beauty (pause) beauty is really tight. (Pause)
120:43:43 Allen: And, Dave, this is Houston. Be advised Jim's got a flap hanging from the lower right-hand corner of his PLSS which perhaps you could button up the next time you're close to him.
120:43:52 Scott: Yeah, okay. It's his water flap.
120:44:00 Irwin: Yeah, I can see that in the shadow.
120:44:01 Scott: (Back at the MESA) Yeah, we're going to have to do some cleaning of him and get that dirt off so we don't have thermal problems. (Pause)
120:44:10 Scott: Take this (entire TCU pallet) out. (Pause)
120:44:16 Irwin: Okay, I've got a tone again. I guess it's...I'm just...(Pause)
120:44:26 Scott: What, Jim?
120:44:28 Irwin: Flags are clear. (Pause)
120:44:35 Scott: (Taking the TCU off the pallet with his left hand, without much difficulty) This TCU was wedged in very tightly.
120:44:40 Allen: Jim, all our numbers on you look good down here.
120:44:45 Irwin: Okay. I keep getting a tone. (Long Pause)
120:45:27 Allen: And, Jim, this is Houston requesting an EMU Mal(function checklist page) number 5 procedure when you get to a convenient break point. Over.
120:45:38 Irwin: Okay, EMU number 5. (Long Pause)
120:46:07 Scott: Need some help with that?
120:46:09 Irwin: I think I'll get it, Dave.
120:46:11 Scott: Okay, I'm going to come button your flap here. (Pause)
120:46:22 Irwin: I'd better take a break and find out what's causing the tone.
120:46:24 Scott: Yeah, I think you'd better. Why don't you just go through EMU number 5, and I'm just going to close your flap here. Matter of fact...(Pause)
120:46:45 Irwin: I don't have any flags at all.
120:46:52 Scott: Stand still a minute so I can get this flap, Jim
120:46:55 Irwin: Check my (PLSS feedwater) diverter...
120:46:56 Allen: And, Jim, if you want, I'll step you through this procedure.
120:46:57 Irwin: ...valve back there for me, Dave, while you're there.
120:46:59 Scott: Okay. Diverter valve is in Intermediate. (Pause)
120:47:15 Irwin: Okay, Joe, I'm looking at EMU number 5. (Pause)
120:47:22 Allen: Roger. Use the step that's greater than 3.4...
120:47:23 Irwin: ... do you want me to cycle the Mode Select switch?
120:47:25 Allen: ...and after tone off, cycle Mode Select switch to A and then to AR. No tone...
120:47:36 Irwin: Okay.
120:47:37 Allen: ...no vent or O2 fail. (Long Pause with a momentary, high-pitched tone)
120:48:05 Irwin: Okay, I'm getting a P in the vent window. (Long Pause)
120:48:20 Allen: Say again, Jim.
120:48:25 Irwin: I have a P in the vent window.
120:48:28 Allen: Roger.
120:48:29 Irwin: I'll cycle the fan (switch).
120:48:37 Allen: Roger. Copy you're cycling your fan.
120:48:44 Irwin: Yeah. (Pause) Fan's back on. (Pause) I have good flow, Joe...
120:49:07 Allen: Roger.
120:49:08 Irwin: But I have a P in the vent window.
120:49:09 Allen: Roger. Copy.
120:49:14 Irwin: Keep a watch on it. I'm going to press on slowly.
120:49:19 Allen: Roger. We agree. (Pause) And, Jim, we think we just have a flag and tone problem. All your numbers look clean as can be down here.
120:49:39 Irwin: Well, that's encouraging. (Pause)

If NASA wants to prove that they did land on the moon then all they need to do is give the coordinates of all large items left on the moon (i.e.) Looner bBuggy in particular and then any indepenent organization with a really large telescope should be able to locate these items and see independently that NASA did in fact land there. Which we all know they did not!!!!

Doesn't anyone know how to read anymore?
I particularly like the "any independent organization." You think he's a little uncertain about who runs large scopes, or even what forms they take these days? Next thing you'll know he'll be asking Dick Rutan to just take a look-see.

There are no telescopes on or near Earth powerful enough -- this has been covered repeatedly, most recently here. |

I love how the CTs pop in and make statements that reflect not even the slightest knowledge of the subject for which they claim to have "the truth".
A little research before you post would make you look a little more "intelligent"...don't argue about things if you know nothing about the subject.

It's not up to NASA to prove they did, it's up to the hoax proponents to prove they didn't.

It's up to any claimant to support his claim. NASA has gobs of evidence. But in typical fashion, conspiracy theorists just ignore it or find trivial (and scientifically wrong) reasons to dismiss a portion of it.
