I just put up 5/8s drywall attached to resiliant channelling in my dedicated room on the ceiling. It's very easy to put up if you rent a drywall hoist. They are available at rental supply stores, my drywall supplier had one. It makes putting the drywall on the ceiling an easy task. I used full 4x12ft sheets. I highly recommend spending the $35 to rent the hoist.
You crank a wheel as if rolling up your garden hose and the drywall ascends to the ceiling. Once in place , the hoist has a lock and you can then apply the screws. I used 3 layers of roxal in the ceiling with the resilient channelling and 5/8s drywall, you can't hear a thing upstairs.
Another good tip is to acrylic caulk all drywall seams before taping and mudding to insure the room is sealed. This is an important step.
Getting back to lighting, I used the light boxes from Home Depot designed to go in an insulated ceiling with halogen lights run off dimmers, looks great.
