Tom,
My 2 cents, and that might be over valued:
RUN away from a career as a pilot if you don't absolutely LOVE aviation. This isn't a career you get into if you just kinda sorta think airplanes are cool, it's a career that requires that you put up with a ton of BS just because you are head over heels in love with flying.
It takes a hell of a lot to get to the point where you get a commercial so it's a long slow expensive crawl up to the point where you get to fly rusty cargo planes around in the middle of the night for 20,000 a year and zero benefits. Once you finish that job you might get to fly jets, but thats a slow process, and the pay is still nowhere near the debt you will have incurred. Flying for airlines has only gotten worse in the last few years, and with so many airlines on their last legs, expect it not to get better...
My point, if you only kinda sorta like airplanes, this isn't the gig for you..
I'd suggest that you give it a try now. Work on your PPL now that you are in college. The scrimping, saving and hustling you will need to do will only serve as a nice preview to what you will expect upon graduation from some fancy flight school. If you cannot make the sacrifices now that you will need to make in order to fly, than you are going to be in dire straits when you graduate ER.
Plus this way if you decide it isn't for you, you can quit long before you have massive student loans to pay back and stuck at an aviation college. Quit before you go to ER you end up only having worked your butt off and having missed a few meals out. Quit at ER you end up deep in debt.
If you love it, thats great, and you will have a head start over everybody else, and probably save money over your classmates.
Don't buy any of the flight school BS, I'm willing to bet that almost nobody that graduates those places ends up flying right seat in anything powered by turbojets. (Save for the Mesa slaves.)
I'm not trying to p!ss on your parade, but I do want to give you some reality check. Being a Pro Pilot isn't just about strutting around Terminal A in your aviators, it's a brutally hard climb.
