First, get the 2012 Arizona State hunting regulations. It's free at any sporting goods store and will have maps and info about the stuff you can hunt. You have thousands of acres of state and Federal lands all around you. Only 15% of land in Arizona is privately owned. While I will shoot pests, when I hunt I only shoot what I'm going to eat. Leave the snakes alone as they eat rats. Oh yah, you will need a hunting license.
