With nothing more than a quick peek at your original plan two things jumped out at me.

You should get a better sub than the EP350, and I'd without hesitation get the Denon DVD-3910. You're going to be putting a ton of money into that projector/screen...give it the best PQ you can. Right now that's the 3910. (Ecost has refurbs for about $750)

I'll check in later with exactly what I'd do with ten grand and a dedicated room.
