I think I would try placing the surrounds back behind the seating area & Todd in towards the center of the room a bit. I personally do not like a speaker right next to me blaring in my ear. I like them behind me & creating a larger rear stage. This will also allow the sound to "bloom" & "spread out" before it hits your ears. Otherwise I'd be looking to my left or right everytime an effect happens thinking, "yep theres the speaker!"
So that's just my small, polite 2cents Nezff!! You've got a really wonderful theater.
Ever think about getting into vinyl? I bet that room would be angreat place to relax & listen to some analog!!
