Jamie,
4.1.2 doesn't have Autotune (the error checker) so don't worry about that. And no problems about the other post. Like you said, just try to keep things clean and orderly around here
The reason the button isn't showing is because of the Share button in the top right corner. The Share button was deprecated by Facebook and is no longer recommended to be used and will actually conflict with the newer tools they offer which JFBConnect relies on. Disable that, and it should help.
Finally, one other thing I notice is that the JomSocial facebook integration is enabled. You should remove the API/Secret key from that extension as it also will conflict (though in different ways). For more information on how best to integrate with JomSocial, please see:

Hope that all helps, and good luck with the unveiling!
