Livin, some excellent observations above, especially that your room is too small to expect to achieve really excellent soundstaging.
A couple of observations, things that I have done successfully in the past. In addition to triangulating a speaker listening position set up, as close to equilateral as you can get, you need to kill (deaden) those first side wall reflections. You can use deadening materiels but they may not be nearly so successful as using extreme toe in, that is toeing in the speakers so that the axis of the speakers cross well in front of your listening chair. That and pulling your speakers out into the room at least 3 ft, more if possible, should help a lot with imaging. It wouldn't hurt a bit if you put something on the side walls to quiet down (breakup) patterns from continually reflecting side waves as they try to bounce about the room. BTW, using this extreme toe in also gives you a broader usable, but not ideal, off center stereo listening for someone sitting in a chair next to you.
Try it!
