Robert-
The carpeting is OK if you call it Persian.
Sheetrock is drywall- and you’d only do that along w/insulation if you’re trying to cut the amount of sound being transmitted through the floor. In so doing you’d be transforming the basically non-reflective joist situation into a highly reflective ceiling that itself would need treatment to make it non-reflective again. Fageddaboutit.
By strapping I mean 1x3 inch (3/4 x 2 ¾ actual measurement) boards, which are quite cheap, going from ceiling to floor, with 1†gaps between each board. Even more effective if you first run a couple of horizontal boards at the top and bottom of the wall and then attached the verticals to them, leaving a ¾ inch gap between the wall and the vertical strapping. Fairly ugly, but quite effective; use nice wood well finished if you want the esthetics to match the sound quality or alternately hang full length wall curtains to hide the strapping. Panels are NFG- what you want to do is eliminate your current situation, which is flat walls that reflect sound, and get highly textured walls that diffuse sound. An even better route is to use 3†or 4†PVC pipe sawn in half lengthwise, installed with the round side outfacing, finally painted with a sand textured finish, but that is a lot of work and money. The goal is to minimize the area of any flat surfaces within the room, and replace them with curved surfaces if possible. Your room might not be as large as the Royal Albert Hall or the Hollywood Bowl, but the basic design theories are the same.
You haven’t mentioned speaker placement. If bass is too heavy don’t have them close to room corners or sitting on the floor, and don’t have them symmetrically placed- keep the distance from each cabinet to the room side and rear walls at least 6 inches different than the other, so that they won’t excite room nodes at the same frequencies. You can also use Allison effect (out of phase cancellation from wall reflections) to tame LF room resonance- try moving the speakers further from the rear wall and see what happens.
