Video tutorials from here, Digital Tutors, and Gnomon will be your best chance to get it all down and learn all the ins and outs that you can without actually going to school for it. Those tutorials and a lot of time. You might want to make sure you have a lot of hair growing out because there will be the occasions where you must pull some out in frustration only to find that it was something very simple that you forgot to do.

Time, dedication, the two things you need the most with trying to complete a project like that. Believe me I keep attempting and then scrapping that idea and trying a new one. Don't let it scare you though, you can conquer it.
