I don't think as individuals blocking IP addresses is a very good idea, not only is it going to be something a lot of people can't do it's also ineffective as these addresses roll over pretty quick.
Making sure the URL in the address bar looks like the site you think you're accessing is a better idea. Asking yourself why you're being prompted for a login, if it's what you expected to happen or not. Having different passwords for services like Facebook or MySpace and then not storing data on there that doesn't need to be there etc are all better ideas.
Not installing applications into facebook that you don't need may be the best idea of all and not spamming your facebook friends with invitations would be nice as well :D
