ReclaimPrivacy.org is a Facebook Privacy Scanner which will scan your facebook settings for you and show you any issues with it, and give a one-click fix to fix them.
With the backlash against Facebook lately, this is a great looking tool that works nicely. The only complaint I have is that it will just fix the issues with one click, without actually telling you exactly what it's doing, in case you were wanting to keep it that way, or tweak it. Still, perfect for your mother/sister/kids/grandmother who you don't want to accidentally share out a bit too much!
