Greetings and welcome to the site.
Aside from what has already been said, you might also try looking at Newbie Central, Tips, and Faqs on the Home tab. Those particular sections might also be helpful to you. There is also a thread in the General Info section called "Starting Out" that might also be of use to you.
Another good idea would be popping into chat, if you still have questions for which you couldn't find answers for on another section of the site, and asking some of the members there for assistance.
Covens are also a good idea. If you go to Groups tab there are numerous covens that would be willing to help you. I would suggest reading over the coven profile pages and find one that you feel offers what it is you're looking for and then apply for membership.
