Setting up Buddy Press and Q&A for my students

I have a WP MultiSite and I've installed/activated BuddyPress, bbPress, Q&A, and Blogs and Users plugins. I want to create a set of Q&A gamified forums for my students. I also want to batch generate student blogs and register them as users for my network so that they can create profiles and interact with each other. Additionally, I would like forums and blogs to either be password protected or private (so that only registered student users can access student generated content).
I'm having trouble finding all of the settings I need to configure this. I would like someone to help walk me through this process. I've enabled support access.
