RE: deer proccessing
You can go on Youtube and find some basic videos on gutting a deer. I would reccomend talking to a fellow hunter who has done it before, and even possibly hunting with a friend or someone to see how it is done in person. In terms of what is the best part of a deer...one word: Backstraps. These are essentially the "filets" of venison. But seriously all the meat is good, when taken care of properly, and prepared in the right way.
