Yeah with a new dedicated room from scratch, your wisest bet is by far professional consulting! A sonic nightmare awaits most in your shoes, simply from lack of knowledge. And there's LOTS TO KNOW in doing this stuff right!!!...most do it very wrong, even with the level of gear you've chosen! And you're going out of your way, you want to do it right.
The room, setup, speaker, seating, acoustical treatment considerations, calibrating, tweaking, power conditioning/distribution,and knowledge and experience will be at least 2/3's of the overall result!
Getting "input" from most will confuse, and you'll still know very little!
consult those who've done this for years, and often!..and on a high pro level for aliving. There's no substitute.
Basically, there's a bagillion ways to do it all wrong, and end up with poor to mediocre audio/visual. I know, I've done hundreds of systems, and lived this stuff for years.
Anyway, good luck.
Basics for you, should you go it alone, are to read all the back issues of "Home Theater Architect" in Stereophile Guide to HT mag, since '98! Also, go through "master Handbook of Acoustics", Home Theater Builder(OK), AV Interiors pertinent atricles(more of Russ Hershcelmann from SGTHT and HT mag), etc. Still, better yet is to consult.
BTW, Russ Herschelmann offers training courses, and he's the premier in the world. Rives and PMI also do consulting, as others. In short, it's simply too much to consult it all out to you on a website for free!...and small room acoustics is an artform and balancing act to get "special"...which is what you want.
Good luck
