Medtation, energy work and basic ritual, in that order. I recommend Silva Life Systems (http://www.silvalifesystem.com/free-lessons) for meditation and some form of Chi Kung (www.taichi18.com) for energy work. Basic ritual is going to depend on the tradition you choose to follow. It could be the LBRP, opening of a circle, honoring the gods, etc.
Do the meditation training first. When you have finished that do the Chi Kung. While you are doing these, start to research different traditions. If you feel your calling is in Wicca, start there, but it wouldn't hurt to take a look at other traditions as well. When you find the one you want to follow, it will have basic ritual work for you to do AFTER you finish studying Chi Kung.
