I'm a little confused, I assume you watch from your bed? If so, you have the speakers on the left side of the room labled as "right", and the speakers on the right side of the room labled as "left"? Where do you live?
Why would you not want the TV in the center of the room, where you have your bookcase? That way, it is lined up with the rear surrounds. Now since your bed is against the back wall, you may not want to go with 7.1 setup, but I would move your left/right surrounds to the left/right of the listening position. Also, I think the sub needs to be moved instead of hiding it in the hallway? You have a very interesting problem.
