If you're going with a pull down screen you could opt for a 3rd M80 as your center rather than the VP150.
If I had a dedicated theater, I would make it look cool - a bare room filled with AV equipment and a couch would be disappointing no matter how good the equipment performs.
I'd go generic on cables and wires to save money for stuff like built-in cabinets, two tier seating (maybe with a tall poker table and barstools behind the second tier?), wet bar, wall treatments, soffets (sp?), fancy lighting, etc...
That's what I picture in my next house, anyways.
Good luck.
