Joe,
First, you will need to enable the 'Social Profiles - Community Builder' plugin. Then navigate to the JFBConnect > Profiles > Community Builder tab. From there you will be able to set which data will be imported and mapped to each user.
Please see the following link for more detailed information for setting up the CB Profile Integration:

This should get you started, but let us know if you run into any problems.
