Which plug ins to use

Can someone please clarify….

Buddypress / MU site install.

Is this correct?

Membership plug in to manage sign ups & memberships & access to buddypress

Pro Sites to manage blog creation and other support features….

I am having trouble figuring out how these two plug ins work together…

Is there a tutorial…

I have also posted a request for someone to pay as a consultant to help me… I need someone for a couple of hours to set this up for me I think…
