So my roommate is moving out

(ya right!) and i happen to be getting her big bedroom. The room measures approximately 18'x10.5'
Since this is significantly bigger than my current room, im thinking about moving my stereo from the living room to my bedroom as long as i can still have space for my bed and desk. Does anyone have any tips or links they would like to share on setting up my stereo for optimum sound and limiting reflection of waves etc. ? The system i have is just 2 stereo floor standing speakers, no subwoofer.
