Wow, what a project! The most frusterating part is trying to plan for EVERYTHING!!! Without a doubt once you get the floor down you will think of something else you wish you would have put down under it, that's a given. Also you better make damn sure you like the positioning of everything, because once you lay the floor you'll be pretty much stuck with the arrangement of the room! LOL, hey I'm not trying to be a downer here at all, just speaking from past experience.
I thank God for my attic, it makes everything a total breeze. However once you get this project done that should be a great looking (and sounding) room. Vaulted ceilings may not be very efficient (harder to heat, and not as easy to wire up), but they do look very classy, and give an over all feeling of being more spacious.
