Do your homework first, by reading books such as those by Bradford Angier and Mel Tappan. With that done, you can put together the gear you will need. Learn to set up snares, start fire by various methods, hunt, fish, and build shelter (practice on weekends). Learn what you can/can not eat in the woods. Summer is not so bad - winter is the real test. Go watch Jeremiah Johnson to see what can happen in the off season. Oh, and I almost forgot, very important: camp near clean, flowing water, and shhiit somewhere downstream.
Guns may be over-rated, but I suggest a .22 pistol and a .22 over 20 gauge combination gun, good to do most anything in the woods. Don't go overboard on the knives - a good ax will serve you better than a lot of knives. Get a hunting + fishing license beforehand.
Take EXTREME care in boot selection.
