Sounds way too big for an 11' seating distance (assuming you're talking 16:9, although that would be a big 2.35 screen, too, at that distance). I have a 108" (16x9) screen with the first row at 10' - I wouldn't recommend going any bigger than that - and if that was my primary seating row, it probably would have been smaller...
2. To preserve space at the back of the room for mingling, games, etc. I would love for the theater section to require only the needed amount of space - I do suffer the further back I bring the seats. Nevertheless I want the theater to be done right. Is there a sequence that makes sense such as (1) install screen and projector, (2) play with positioning of chairs to see what distances seem desirable, (3) install riser and finish room.? What is a good order to do things in?
Figure out your seating, your screen size should be based on those distances. Use the screen size calculator to get an idea. You can finish the room, hang the projector, and test the screen size if you want before you commit to one. But you should be able to get reasonably close beforehand - that testing is just for fine tuning perhaps between a couple of size choices. At that stage there's some personal preference, too...
3. While I dont need to "sound-proof" the room, I may want to apply some sound treatments. I assume I can do that later in the project.
Yes, acoustics are part of the room finish (inside the drywall), but how you want to apply your acoustic treatments may affect your finish work (outlet placement, areas for bass traps, etc.).
