Worked on the ceiling mount for the projector a little more. I think I'll be ready to install it by tomorrow.

I also stopped at the fabric store and picked up a couple samples of different material for the big screen. I bought more blackout cloth, and some silver satin, both about 1x3 feet. I taped them onto the wall for comparison and this is when the yellow from the wall really stood out. The white blackout cloth was way too bright overall, especially in the black areas. And the silver satin cloth looked incredible. It had just enough reflection to it for the whites to look bright and the silver color really made for some dark blacks. I think this is the way to go. I'm either going to stretch this over the existing frame I built or add some thin door panel to the frame and stretch the cloth over that to ensure a perfectly flat surface.
