Hi Benjamin,
Welcome!
Online, this forum is probably the best place to start. You'll find a very supportive community, here, with photographers from all over the world. Start with the forums section; there are countless discussions on all aspects of traditional photography, in all formats.
Following the advice of the above posts, I too, highly recommend going through the local bookstores and libraries for information and inspiration. Pick up a few books that interest you. There's nothing like having some solid references to fall back on. Don't look at just books on technique; peruse as many monographs as you can to see how other photographers work and "see". Also, visit local museum and gallery exhibitions.
Another thing to consider, is to take a class or workshop in the Philadelphia area. It's a good way to start picking up "best practices" and getting a feel for the medium, not to mention discussions with other participants. There are many great schools and organizations, there. Perhaps someone from the forum can recommend one.
Good luck, and have fun.
Andrew
