Be certain to check the Room Acoustics forum (sponsored by Rives Audio) on Audio Asylum which has a ton of information. Ethan Winer (musican and owner of RealTraps) is a frequent contributor there and his web sites are a "must" read for those interested in room acoustics and treatment. The Rives Audio site is also an excellent resource.
There are a number of suggestions that could be made, but educating yourself a bit first will probably be the most useful. You may also want to consider doing some rough room measurements using the Radio Shack SPL meter and Rives Test CD. They can be purchased for less than $75.
One thing you might want to try is Jon's "down and dirty" bass traps which are essentially bags of rolled insulation stacked in the room corners. Not pretty, but inexpensive and quick and they will give you a hint at what's possible.
I've treated my room with custom bass traps in all four corners using a design based on Owens Corning rigid fiberglass panels. Also treated first reflection points and some other areas. The improvement in the sound is significant and at least as important as any component upgrade.
