I quite like Facebook too but can see its many pitfalls. Keep your privacy settings to friends only for everything and watch for anyone spoofing you or Bering spoofed.

As for photos, I think it has been said before. If the area is public then it can be photographed. If you are in a public area, you can be photographed without permission. If it is a private area or function, the photographer should seek permission. None of this has anything whatsoever to do with Facebook. They may take take time but I know from experience that Facebook will take down something if you have a genuine complaint about it.
