Wow, sounds like you have several issues to sort out. Could you describe your room and speaker placement? Have you tried any room treatments (bass traps, absorption panels, etc..)? Have you tried to move your speakers around? Maybe something as simple as pulling them out into the room and away from corners would clear up the bass and vocals.

The noisy floor is easy to fix if you have access from underneath. You can either cross-brace the floor joist, shim between subfloor and joist, or use special break away screws from the top. The break away screws are about your only option if access can be had only from the top side and don't want to mess with pulling back carpeting. If, however, you have carpeting and don't mind taking it up, you can screw the subfloor down with many pounds of 2" screws (about every 6".)

One other thing to try: get a test disk and play each frequency at a pretty high volume and listen for sympathetic vibrations. I did this the other day in my listening room and could not believe how many other noises came from stuff in the room itself. At 90 hz one panel on my computer hutch were really shaking.
