“Ok, is there a addin to manage bbpress from buddypress so i can make all the sub-forums, and categories i need? I’ve got a add-on i from here called new bbpress admin, but how do i import everything through that into buddypress on wp?”

No there isn’t. If you need an admin panel, stick with an external install of bbPress.

Um, before i go any further should i change to wp mu or stay at the regular wp?

It doesn’t matter.
