How can I use Membership Plugin to lockdown BP Pages?

Hello guys!!!

I'm runing a BP+WPMU project here, so, the BP site is the main site, I don't want users who are not logged in to see member profiles, groups and other things, but they can see the homepage and search for blogs, so, I don't want they to see just some pages...

For monetize my project I use Pro Sites, so, I need membership just as a lockdown buddypress tool, is it possible?

Thanks

PS: Is there some whay to me to protect user profile to be indexed from google?
