Any best practices instructions for using JFBConnect from SourceCoast

I subscribe to SouceCoast and have installed but not configured JFBConnect onto my EasySocial site. I am using this mostly because I want the logins via multiple services.

I am assuming a couple things but want to make sure.

1) I suspect we should turn OFF your facebook login integration in order to use theirs.
2) I am wondering if their SCLogin would replace yours?
3) I am wondering if you recommend we use any of their other tools like the likes, shares, etc. or if it is best that I just use their tools for the login capabilities and use StackIdeas tools for the rest.

Thanks, Sean Carney
