There's not an easy way to add the FB Connect button to the CB module, but the CB links should be easily add-able to the JFBCLogin module. Let us know exactly what you're going for.
I also notice you don't have an active subscription. If you purchased under another account, please let us know and post with that account so we can prioritize your support. Additionally, if you aren't using the latest version of JFBConnect, v2.6.x, it will be more difficult to support you as there's a lot of new Community Builder fixes and updates in that series.
