Here are some suggestions
I gave to a guy a few days ago for setups costing roughly $2.5k. Any one of those setups will be a lot better than the speakers you are contemplating.
As far as a AVR goes, I would get whatever Denon, Yamaha, Pioneer, Marantz, or Harman/Kardon you can comfortably afford. They will all have ample power for your speakers unless you go with the entry level models. Onkyo is harder for me to recommend because of how hot they get and their reputation for sub-par customer service, but if you don't have any problems with your unit they are a hell of a bang-for-the-buck.
It's hard for me to recommend Optoma, my own HD20 has had to go to their tech support about once a year since I have had it, and last time it cost me over $400 to get it fixed. Next thing that goes wrong on it, I am going to just get a new projector. Like Onkyo, Optoma is great bang-for-the-buck when it actually works. although I wish my HD20 had better black levels. If I were you I would try to get a projector that has better black levels than the HD20/33.
For the screens, if you are willing to DIY, you can save a hell of a lot of money. Check this message board
out. It is very easy to make a great screen inexpensively. However if you are willing to spend a bit more for convenience, a lot of people hold Carada
screens in high regard for their value.
For blu-ray players, don't spend a lot on one, get a newer Panasonic or Sony or brand like that, but its probably best to avoid the cheapest models.
