Welcome Christina! We were all a little overwhelmed when we came here. You're in good company. Have you checked out the Newbies board? That's a good place to start. Here's a link: Newbies info/introductions - CurlTalk
There is no magic wand and no one thing that works for everyone. Your first move will be to get your hair healthy. For most of us, that meant giving up harsh, damaging sulfate shampoos and getting moisture back in our hair.
My best advice is to read as much as possible. Don't get overwhelmed, it will all fall into place in time. Be patient and experiment with new techniques and products. Piece by piece, you'll find what works best for you.
