I have a room similar to yours but I built and entire building for my theater. I am on my 3rd projector/scaler combo and I would highly recommend it. It is the new Meridian/Faroudja setup and is an incredible value for the money.
I also think you will have a blast with the buttkickers as well. I saw somebody listed the JL Aduio Fathom 113 subs as a replacement for them which is not truly the answer. The JL subs are the best I have ever heard without a doubt and I just sold my 113's and have a pair of the JL Audio Gotham subs set to be deliverd in 3 weeks but the Buttkickers still add a real "kick in the butt" so to speak that the subs can make you feel in your stomach but dont give you that "Disneyland" magic that the buttkickers can give you.
