Hope that cleared up your issue with CB, but if not, let us know. I couldn't be certain from what you posted, but it sounded like it.
Regarding the login page, there's no way to skip it once you're on it. If you want every user to bypass it (as is done on this site), you can set the "User Creation" setting to "Facebook User Only". If you have it as "Full Joomla User", that short registration form will always display. However, you can hide the email address field (since it's imported from Facebook) with one of the config settings, leaving just username and password to be filled in. Hopefully, one of those options is acceptable for your needs.
Finally, we are the best

Hope you're happy with your choice, even with a few stumbling blocks along the way. Good luck with your launch tomorrow!
