Custom Build Listening Room

I am building a house with a 28' x 16' game room that I want to turn into a home theater / music room. The room is rectangular with three windows on one side and a coupple of doors on the other (at the long sides of the room). My equipment is Revel Salons, powered by ML 336, C30 and will get the Embraces powered by an HPA3 for center and surrounds. I would trully apreciate any recomendations (with the limited info given) as to any "treatments" to the room that would improve the final result.

Many thanks for all your comments!
