Ford F-150 just smacked my Dart!

Having never been in an accident before, I would like some procedural advice and/or suggestions from those who have. Thank goodness the guy has insurance. Obviously I need to get some pictures today but then what? Do I just start getting estimates from body shops? Do I call his or my insurance companies? I know it sounds silly, but I just don't know.

I don't want to get screwed over by an "at fault" Chevy lover in a Ford truck. Now that the initial shock has worn off...I'm pissed!
