Boy you have some learning to do. Room is 50% of the final sound and you can over do it, and it will take some time.
My advise is start small, hit the corners on the wall behind you speakers, the center area wall behind your speaker and then listen, then grap a mirror and find the 1st refection point on each wall then grap a rug or something and dampen that area and listen, play with that setup for awhile, remove a panel and listen again, and slowly your ear will be trained to pick up the changes for good or for that so good.
Use google and research on line and read. Every room is different so you have to looks at yours as a one of a kind with its own needs.
