I'm glad you mentioned you're using RC1. The renaming of the libraries for JFBConnect took place in RC2, so upgrading to that should fix your issues. Alternatively, JomSocial 1.8.3 (pretty sure on that) was when they changed their library names as well to prevent issues. For JomSocial, yes, you simply want to remove your API/Secret keys. They still load up some Facebook functionality, which I wish they didn't do, but you shouldn't have any more problems going to RC2. Upgrading is super simple (uninstall, reinstall)... all your settings remain.
As for the review, we'd love it. We don't base support on those that review us, so don't feel required too, but it helps spread the word and definitely helps continue our rapid development pace by getting more interest in the product. Thanks!
