And now...onto some real advice for bdwyguyhottie.
Yes. Get headshots done. They will help you when it comes to auditioning for summer stock and such. Plus, if you come to NYC for an internship one summer, you'll have them on you and you can cast your line in the big bad city (avoid at all costs the freshman fifteen. keeping the 'hottie' part of your name will only help!)
The idea of a student photographer is excellent, but, as it is with buying a new car and picking a plastic surgeon, do your research. Meet with a couple of them and see with which one you click best. Natural light is wonderful, solid shirts with a texture are recommended and please remember that the picture is representative of you and not this photographers artistic life up until this point.
As for agents, unless you are going to be in a major theatrical/film center, I'd advise against it. Concentrate on being a strong, well-rounded actor. HOWEVER, if an opportunity comes your way you feel you can't pass up, take it. They don't always come along.
