Events...Mail Chimp Integration

Two Questions:

Main Question: Under Settings...Extras is there a way to associate the Mail Chimp Plugin with the Events Plus plugin?

We would like to capture the contact info from the attendee and send it to Mail chimp so that we may send promotions to the attendee for future events and the client prefers mail chimp.

Side Question: If I check Allow FB and Twitter Login is there a way to capture their contact info if they login this way and then sign up for an event?

Please advise re. BOTH questions.

Thank you.
