Sounds like you are begining a fun project JODY!
If it were me the first thing I would do is skip the bar....I love beer /forum/images/%%GRAEMLIN_URL%%/tired.gif and what not, but all the people who I know that have a bar usually end up using it for storage or to place junk on. They also take up a ton of space. Thats just my opinion of course.
The other thing I would do is 3/4 inch ply wood the whole room if possible, this will allow you to move heads wherever you want without constantly trying to locate a stud etc.... Maybe to late to do that if the sheetrock is already up. For a shed freak like you I would definately put a ledge around the whole thing to display sheds.
Cost? I dont have any idea, but I would guess around 10K for flooring, wood, TV, couch ....it would all add up pretty fast.
I have a wood ceiling in mine that I think is pretty mint.
Anyway, good luck and make sure you post pics of the finished project. /forum/images/%%GRAEMLIN_URL%%/cool.gif To bad you don't leave more towards NC KS, we could hook up for brewsky in NOV. /forum/images/%%GRAEMLIN_URL%%/grin.gif
