Redirect to author profile after fb connect


I want to redirect users after login to their front end profile page, how do I do this?
I am using the following code in functions.php but I think the setting in Ultimate Facebook is causing a conflict -
function myplugin_registration_save($user_id) { if(isset($_SESSION['selectedWHS'])) {
$value = $_SESSION['selectedWHS'];
} else {
$value = 'none';
update_user_meta($user_id, 'whs_list', $value);
return get_author_link($current_user->ID);

Also, how can i fill user's profile information in wordpress from facebook by default? I noticed that the information is stored in usermeta but not filled in the profile.
