It sounds like it's not about being connected to facebook but being connected to the internet. You can play offline but limited to what is stored on your device. Your friends games are on the server, not your device, you need internet connection for your device to retrieve the information from the server.

As for zombie facebook friends. I believe the game adds your facebook friends automatically if they have a game. If you want to delete your facebook friends, you can try this. (I don't have facebook friends who play the game to see the results but logically this might help. I'm not sure how it handles seeing you on your friends' friend lists but not seeing them on yours.)

You can try disconnecting facebook on your game. To do this go to settings (the little gear in the upper right corner) and in the pop up it has a little blue bar that either says Connect to Facebook or Connected to Facebook. If it's already connected, click it to disconnect. Now hit Connect to Facebook. Log in to Facebook, click where it says Review the info you provide, uncheck friendslist, then hit Continue as [insert facebook name here].
