The first thing that struck me looking at your room layout is that you're sitting almost in the middle of the room! Which in theory should coincide with a major null in a perfectly rectangular room with close to even dimensions. The first thing I would have done without adding any EQ, was take some more measurements further back and forward of where the sofa presently sits,...but that's just me.
Then again, you've located the sofa and speakers for optimal surround sound too, so if you want to adjust the response any more you'll probably need a BFD.
