The only hole that I made in the drywall is in the front most part of the ceiling and it is just enough to get to the vent in the side of the house. I do have a hole in the rear of the theater where I put in that really large fan in the ceiling. When I get to putting in the air return, I will definately be running some wires for ceiling speakers. You are right, once you start messing with drywall, you might as well finish.
