How Do I Install The Membership Login On My Site

Ok I've installed Membership and Buddy Press on my site and also the theme. I can see the theme, but I don't see where to make the membership subscription levels or login info live.

Once I fix these couple of things I want to be able to have my members offer their customer Pay Per View and subscriptions to their content on my site. I will download the Pay Per View app. Any idea how I would do that? I also want to add a live streaming video app from Video Whisper and wanted to know if this a good app or do you have other ones that you could suggest for live streaming and on demand.
