I haven't done much with this sort of thing, although I've done enough acoustical calculations to know that it's in many ways more dark art than science. Your comment about the link to RAF's site reminded me of an old 6-part (edit: OK, 5-part plus photo gallery and addendum...) article on dvdfile.com that you might enjoy: Mr. Blandings Builds His Dream Theater . It gets into a lot of the room design and construction stuff that you are asking about.
