There are a number of factors to consider. -Is this a finished room, if not who is going to remove all the furniture and cover the flooring. Are you going to re-paint the walls after the job ( they will almost certainly need it) . Actuelly remiving the drywall is a fairly simple job, but all the other things including disposing of it make giving a figure very complicated.
This varies depending on location, size & type of job (wall? ceiling?) so get several estimates.
Fourteen sheets for the walls. Twenty one and a half for the ceiling.
how much will it cost to rip out 1300 sq ft of drywall and insulation and replace said
That's a waste of time . Call 2-3 drywallers and get them to give estimates. I always do that and get a faster, more accurate answer than I could ever come up with myself.
1000 sq ft should do it
This varies depending on location, size & type of job (wall? ceiling?) so get several estimates.
Removing a wall cost $250 depending on the size. Labor may cost as much as $800, and $75 for ceiling joists.
It will cost about $1.40 per square foot to texture drywall. The total will generally depend on the amount of texture you're looking to get done on your drywall.
Using the Elegant Tray Ceiling System it would cost $402 plus 9-8' 2 X 2s, 1/2 pound of 2.5" drywall screws and the rental of an 18 or 23 gage air hammer.

Depends where you are , but usually about 20% more than regular drywall.
$4.44 for a sheet of 4x8 1/2 in drywall at menards in Morris Illinois
The cost of repairing drywall damage would depend on how much damage is done. If you were to buy the drywall it ranges from $10 to $30 a sheet. Plus if you hired someone then it would cost more for labor then it would if you did it yourself.

If there's any question about whether or not a drywall anchor will hold on the ceiling, the best thing to do would be to find a ceiling joist and use a long screw to go into solid wood. (Use a stud finder to locate the joist.) Hanging on a ceiling is more dangerous than hanging on a wall since things that fall can fall on people or pets. If you HAVE to hang just in drywall, use the strongest anchor you can get (i.e. one that expands like a butterfly after insertion, or the type that flares out like a flower when you tighten it). Your local hardware store can help with what's a reasonable weight limit.
Drywall labour costs depend largely on where you do them. Labour costs across north America differ locally.
