Okay, I am not too familiar with residential constructions. I know that the master bedroom (second floor) of my home is directly over the garage (first floor). Now, I know that if I were to open or tear down the drywall ceiling in the master bedroom (on the second floor), then a lot of insulation would fall down. However, if I were to open or tear down the drywall ceiling in the garage (to run wiring, etc.), what should I expect to find? The home was built in 2007, and it is located in the metro Houston area.

I re-did my garage ceiling a couple years ago. Home built 2003, in Southeastern Ontario, Canada, so may not be entirely the same, but probably fairly close. Here's a picture after I had taken down some of the drywall, which gives a nice profile shot:
You'll probably note I used the past tense there. I took all the drywall and insulation down, cut the joists back to make the ceiling higher, installed some network/cable jacks in the rooms above (I fished wires between the joists to get to rooms not over the garage), installed central vac, and then used spray foam to insulate the ceiling, used the old batt insulation to insulate the exterior walls, and finally dry walled and installed some shelves on the ceiling. The room above is warmer, the garage stays above freezing, and both cars and the snow blower fit (though I have to move everything else up to the shelves in the winter).
