Restraining order. Go by the nearest branch of the police department and let them know what is going on. Even without a restraining order, if they are aware of the situation, they can keep an eye/ear out for trouble concerning you.

Once again, restraining order. Then if he tries to contact you, you can have him picked up. That sometimes works to scare the bejesus out of an emotionally charged stalker, and he calms down.

I have been there. It's not fun dealing with a an ex-turned-stalker, or lawyers, or policemen in order to get your privacy and peace of mind back. But neither is having someone trying to make you miserable or break your arm in a parking lot. Get him to stop NOW, before it goes any further. Keep the paper trail as evidence of what if happening. Show a pattern. If it is escalating, be able to show and convince someone that it is.
