BuddyPress.org

ok, first of all, in Revolution style.css:

#header: padding 25px 20px

(so the topnavbar will show under admin bar).

then You gotta to add to style.css this:

#content: width 610px (or in #postarea)

Sorry if I tell You, but your css is not well integrated between Revolution css and Buddypress css. That’s the main problem if the site looks not so good.

If you need more help you’re free to ask.
