Start by reading the FAQs then do some searches on each of those questions. After you've read everything you can find, post any specific questions in the proper forums. If you look like your putting some real effort into it, and ask challenging questions (that wouldn't be answered easily with a search), you will get help.
Most people here don't like to take the newbie by the hand and walk him thru everything. Most newbie questions are basically asking for someone to type a 10 minute response to their question, when the newb can have his answer with a 2 minute search.
