For point one, you can set it so as to have every tag of you in a post (not comments) be queued for review by you before they show up on your timeline. You can untag yourself during reviewing.

If you think Facebook should automatically recognise your face on other people's public posts (where you are NOT tagged) and blur THEIR pictures, I don't know if that's not just reverse censorship.

On a related point, FB could come up with a system that publishes any image with tags of personal profiles only after all those tagged profiles have approved their tags, or removed themselves, but that might significantly delay the post and inconvenience the poster.

Even if you don't have a FB account, people can upload pictures of you and tag you in them. It won't be linked to an account, but your name will be tagged to the picture.
