Removing unnecessary FB access permissions

Firstly, I'm fairly new to FB Connect so take it easy on me!

When registering to a site using FB Connect, it requests the user's permission to access all their FB data - photos, profile, email, friends etc. This is going to put most people off using FB Connect.

How can I change FB Connect to only request access to profile information and an email address?

Also, how do I access this data once a user has registered to the site via FB Connect?

Standard single-site WP install.

Any help would be massively appreciated!
