BuddyPress.org

What difference does it make if I install WPMU or I make my wodpress theme(version 3.2.1) Multi-Blog-Network enabled?
Lately, I have been creating a WordPress theme (you can see it on one of my domains: http://www.antiquesartgallery.com )
After enabling Multi-Blog-Networking system i can see superadmin area where I can create a blog.

My questions are: I have already created a theme and want to integrate it with buddypress, I’m completely confused on how to go about it?

Further, I have activated buddypress and made a navigation bar with the links of members, groups, discussions, activity. (You can on the top right)

The issue: All my linkings (forum, groups, members and others) are directing me to the home page and to the destination?

After too much of wait and searches, I’ve finally come here with a hope. Please help me.
