My Two Cents:
I have about 6 months worth of professionally hanging drywall experience, here are some tips:
-Two people makes things 20 times better
-Use 2 drywall horses for hanging the ceiling, they are adjustable, borrow if you can. Adjust so that you can hold the sheet up with your heads, ideally just standing straight up, or slightly raising your heals, then nail the edges, screw the rest later, it will hold fine till then.
-Make sure every nail you hammer in goes below flushness of drywall, its a pain to mud over it later...use a drywall hammer if possible, much easier.
-Borrow a rotozip type router to route out lights, and stuff, sometimes you can mark a sheet where the light or outlet may be, then hang it and tack it enough to keep it up, then rotozip out the outlet or whatever, takes a little practice, make sure electricity to those out lets is turned off.
-after ceiling is hung, hang tops of walls first then bottom horrizontally if possible, start on left, move to right, or vice versa i guess, just dont start in the middle or anything.
-use a toe lift to make the bottom piece meet with the top piece perfectly, on both bottom and top sheets, lean the sheet up to the studs, put the nails where they are going to go before you lift the sheet, so that when you lift it up there, you can hold the sheet and nail with one hand, at least the top row so you can get it tacked enough to hold while you do the rest. Not necessary for the bottom but you can do it there as well while you use the to lift.
-After hanging screw your ceilings where you didnt nail.
Essential tools for hanging drywall:
-Tape Measure
-4 ft Tsquare
-small hand hole saw
-drywall knife (box cutter, etc)
-drywall hammer (there $30 but worth it)
-Construction Pencil
-Rotozip (not required but makes things easier)
Biggest Time Saving Tip (hopefully I can explain it right), Place entire sheet against a wall..... measure how wide or tall your piece needs to be mark it with T-square, use your square and use your knife to cut a straight line (not all the way through, just score it) then move the sheet away from the wall, on the back side of where the score was just hit if firmly with your wrist and hold the end, it should break perfectly, then use your knife to score the rest on the back side down the same folded line. This is a heck of a lot easier then using a table saw or any type of saw to cut each sheet, or using a horse and cutting that way,

I have a bunch of tips for taping/finishing etc as well but im tired of typing for the day, I might do that in the next couple of days.
I hope this helps!
