Meditation and studying is a really good place to start. Personally, I feel that too often people attempt to "jump in" without knowing what they are jumping in to. Know exactly what it is you want to accomplish and go from there. It is a process. You have to learn just as you would learn anything else.
Aside from what has already been said, visualization, energy flow, control, and raising. Grounding, centering, belief in yourself, circle casting/releasing, correspondences, etc. I believe that there is info on all of this in the Featured Articles section on the articles tab. Reading through Newbie Central, Tips, and Faqs (on the Home Tab) and the Starting Out thread in the General Information forum should also help you out.
