Yes, XFtoWP has basic custom field support. You can create a few custom user fields in XenForo to collect this information about the WP user on register/sync:
They user fields have to be a certain ID to work when you create them:
WordPress user roles - wp_roles
WordPress user ID - wp_user_id
Last synced to WP - wp_last_sync
First sync to WP - wp_first_sync
Since these fields are possible in XFtoWP, any other kind of data is also possible to pass from WP back to the XF user account. Currently this would require a little custom development to plug your fields into, but it won't take much for us to create a user interface for custom field mapping, which is high on our internal roadmap.
