Currently, it looks like the "Connect with Facebook" buttons just redirect to whatever current page the user has loaded. I'll look into that over the weekend, but the Like and Share buttons are working as intended.
There seems to be a hurdle with instant posting. In the AdminCP, I have a few bypasses enabled that should allow a user to be ready to go via an auto-registration feature, yet this does not appear functional in practice. I'll keep digging, but I may not resolve this before I head to bed tonight.
