I didn't know you brewed (home brewing spiel spoilered)
I'm going to use an Optoma HD26 and ceiling mount it right about where the picture was taken. I'm still debating a 110" diagonal (96" wide) or up 138" diagonal (120" wide). I'm building a partial faux wall about a foot out where the screen will be, and sticking my speakers behind it. Thats the magic of spandex - its pretty inexpensive and makes a great acoustically transparent material. I will fill out the rest of the space with dark curtains (I want easy access to the laundry still, which might necessitate a smaller screen).
The white walls and ceiling tiles are going to be painted navy blue (Behr Very Navy m500-7). The stained wood will stay for now. I think those two will go well together, and will help me darken the room without looking like a dungeon. I'm going to hang a poster over the window.
The rule of thumb with projector screens is this - if you have a really good projector capable of great contrast, use a white screen. If you need to cheat a little to get better blacks, use a silver one (at the expense of over all brightness). The common logic is to get pieces of each color and use one as a backing for another. It prevents light from shining through the screen. And you can test out both in your space to see which one you want facing you.
Seating will be a cornered sectional, sitting right about where the drop ceiling ends. The door to the garage is immediately to the right of where the picture was taken, and I want the seating on that side of it. I'm not into the formal "home theater" seating.
The new receiver is a big debate point. Its a place I can shave a few hundred dollars of the cost by keeping features low. I definitely want at least 7 channels. The new trend is to add 2 more on the ceiling. Dolby Atmos is already out in the wild, and DTS' competing system will show up this fall. Some of the current systems that support the Dolby standard will get firmware upgrades to enable the DTS flavor, but probably not the ones in my price range. So I likely will just go for a 7 channel system and skip the object oriented formats for now.
Then we are going to do carpet squares on the floor.
http://www.carpet-usa.com sells variety packs of color families pretty cheap. My calculations say about $200 to do the whole thing. I'm still mulling if I want greys or earth tones.
