There are plenty of options with a $4k budget. I would probably only spend about half of that on the projector and even at $2k you can find a good quality projector that will last long term. Panasonic and Epson are a couple companies that come to mind that make fantastic projectors in that price range.

As others have suggested, a receiver is a MUST. An inexpensive brand is Onkyo. I would suggest either the 707 model at least. If you want to spend more, then the next levels up are well worth it as well.

I will second the SVS speaker suggestion that Tony made, too. You will want good quality speakers to go with your good projector. Image quality is only half of the movie experience. You're missing a ton without some good quality speakers.

I had a 92" screen in a room of similar dimensions and it felt pretty big to me. Another suggestion that I might make is to get the projector first. Play with the distancing of the projector and also the zooming features to see what size screen works best for your room just by projecting on the wall. When you get a good idea, then you can order the proper screen size.
