Setting up buddy press with membership


I am a newby at buddy press and want to set up a membership site where people will have a profile, they will be able to interact with other members but I want to be able to have the paid part as access to the forum.

I have a couple of questions:

I presume this is possible, I could give access to info on the site with the forum password so only paid access could see it?

My question then is do I need to connect membership or buddy press at all or are they separate on the site and disconnected…I presume they operate seperatly?

Also I want to keep this simple so cannot I remove some of the buddy press features and keep others?

thanks for your help,
