Photog had some great suggestions. Listen to what he had to say. You will have to buy or borrow a camera FOR the class. They will have you buy the books you need, so do not even worry about that.
Now this is just my opinion and only that, you may want a DSLR, but if you are just starting out I would really suggest you start out with 35mm film and not digital. If you really want to understand the nature of light and how to use it to your advantage, it is best to start with a traditional film and darkroom class. You will not believe how much working with an enlarger helps you understand how photography works. I found my first camera, a Minolta XA7, in a 5 dollar box at a tag sale. A $20 cleaning later and I was good to go. Won my first contest (a National Geographic one) with it 5 months later. I still prefer that little no nonsense fully manual camera over my DSLR. I dropped that thing in a deep tide pool in Baja, a steam vent in Hawaii, a few snow drifts in Austria and New England, dropped it a few times on rolling talls ships (I have butter fingers at times), and it still works perfectly with only minimal cleanings. Using a fully manual camera is the perfect way to start out. Working in a darkroom can also help you understand how to best use Photoshop and its tools. I guess I just prefer grain to pixels.
That's just my opinion. Ignore it if you would like. Any class will help greatly.
Another great way to enhance your understanding is to study the greats. During my high school and college years, I was heavily influenced by Margaret Bourke Wright, Daido Moriyama, Harry Callahan, National Geographic, and German Expressionist Films.
If you want to check some books out now, then here are three from college that I liked.
The Photographers Handbook- John Hedgecoe
Photography- London, Upton, Stone, Kobre, Brill
Digital Photographers Handbook- Tom Ang
You can't go wrong with books from National Geographic. I have bought several and they are great for travelers like us.
One last thing. Since this will be your first CAMERA, I would highly suggest you do not buy new. Look on ebay, craigslist, or even better if you have local camera shop near you check them out. They might have used stuff for great prices. That's what I do at times. I'm not talking about Best Buy, etc. I mean a local Mom and Pop place. The kind of place with no wall or floor space for anything new, the kind with carpet older then you, that smell like your local army/navy store. Those are the best kind. They will have years of knowledge to help you. That's if you can find one
.
Anyways, good luck. You will love the leap from point and shoot to SLR/DSLR
