I'd agree with the previous posters on having some treatments on the front and back wall. From the pictures of your system, it seems like your speakers are quite far from the side walls. If that's the case, treatments on side walls may not be too necessary. I would think the biggest impact would be the front wall and placement of speakers. Your TV at the middle isn't helping too much and I would concur with Newbee's idea. It depends on whether you would be willing to sacrifice aesthetics by placing some absorption panels behind the speakers and/or TV. As for the back wall, you can experiment with either diffusion(tall CD racks or book racks will do) or absorption.
New speaker placement
I'm trying new speaker placements
The speakers are to the R & L of my 36 inch television
and i'm sitting nearfield. My ears are 5 1/2 feet from the tweeters and the speakers are approx 3 1/2 half feet from the back wall (see my system page to get a visual)
I'm interested in getting advice on what room treatments you suggest for this room
