And I'll also add: d) Never associate your real name with your FB account.

I use my first name plus a family name that matches my middle initial. It's generally recognizable and accepted by friends.

When I first set up my account this way (items A through D) it did seem a little "tinfoilly", and this last measure still does to some extent. But since Facebook doesn't actually let you delete your account, I'd rather err on the side of prudence. It will be nice to at least approximate a hole in their databases if their policies ever get too onerous.
