Re: bbpress & wordpress integration
Integration works fine.
If you are using WordPress 2.3.x you need bbPress 0.8.3.x and if you are using WordPress trunk (2.5 alpha) you should use bbPress trunk r1075.
Essentially cookie hashes and paths have to be sync’ed and a plugin is needed on the bbPress side to set WordPress roles if they register through bbPress.
I’ve assembled most of the details here:

Or you can comb through the integration tag here:
