Start reading through a bunch of the threads here. To answer your 2 questions, yes and yes. But there's a lot more to it than that. Do several hours worth of reading before starting to ask a bunch more questions - most of your questions will have already been answered multiple times here already.
Then, once you have a clearer picture about what it's all about, come back and ask more specific questions.
