Check out LEM Products ( LEM Products) for a variety of game processing goodies. They have several books and/or videos that I understand are quite good. I have never personally seen them though. You'll find that game processing is a personal thing, and will develop your own style. The important thing is to remember that good meat starts the moment the critter hits the ground. Keep it cool and clean and you'll be ahead of most of the crowd. Second, be sure to trim all the fat, silverskin (or whatever that junk is called), and tendons from the meat. I debone everything too. Nothing but pure meat goes in my freezer.
You'll need a good cutting board and knives. I actually like those offered under the brand name "Bakers and Chefs" at Sam's Club. They are of pretty decent quality and the price is right. You can get by with a hand grinder, but if you expect to do more than one little critter per year, save the time and effort and get a good electric one. I bought the 1HP model from Cabela's and have been very happy with it. You can get fancy with vacuum packing or other storage methods, but I prefer regular old freezer paper. I double wrap everything and get at least two years of freezer life from properly cared for game.
There is other gear you can get, but start simple and add to your collection as you find out what you like. If you have any more questions, feel free to PM me. I take great pride in processing game (usually about 12-15 animals per year) to get the best possible tablefare, and welcome the opportunity to discuss it with others.
