I hadn't previously seen your thread before. Just wanted to chime in and say that you made nice use of the space with the budget that you had. It's funny I had the same budget as you, and like you that was supposed to include everything. Luckily I was able to get most of the major things done with that budget, but when it's all said and done I have pretty much doubled my initial allowance.
As far as the proj. mount, I say paint it the same color as your walls.
