Vern has a good list there for someone that's on the move. There's been other great advice about learning what edible plants could be available. Be sure to really educate yourself for the environment you choose. I'll advise staying closer to home for the first 'camping trip'. This isn't something to take lightly. Many an experienced hiker, hunter and outdoorsman has been 'surprised' by the elements that our world can bestow upon us at any time. If you haven't been taught how to make weather proof shelters in correct locations using local vegitation, tie reliable knots, dig latrines, find and purify water, how to sharpen and keep knives and axes sharp, and most importantly how to build a fire when all of your fuels are wet, how to cook on that fire, then you need to do more than reading books. You need to learn and practice these things. Map reading, improvised hunting meathods, short term weather forcasting, are important too.
If you haven't become an experienced hiker/camper, then your choices of boots and clothing may not be optimal for your journey. Everyone is different. Although I hunt using boots that are mostly synthetic composition since I return to a nice camp trailer daily, If I was to do what you're talking about, I'd switch to a leather boot with GoreTex sox, and if up north or in marsh land, I'd include something like Xtratuffs. Not the steel toe version. Wool is your friend. Vern mentioned a 'down' sleeping bag. You do need to know how to care for one. I prefer a Zero Degree Qualofil bag used with a waterproof Bivwack sack and a 2 ounce hammock suspened under that same poncho when on the move. When at one place for a while, You need to learn how to make a comfortable bed from local items that will insulate you from the ground not robbing you of important body heat. Caribou mentioned more than one knife. I'll second that! And cord. ..Nylon stretches. Dacron doesn't. (not near as much) Cotton freys and weathers poorly. Hemp cord lasts well but is not as nice to work with. DUCT TAPE. Gosh, how did our forefathers do without Duct Tape?
What season you go play in the woods will have bearing on what your successes are. Summers can be warmer during the day, cold at night. Winters, wet and cold all the time. Are you willing to gather, cut and split wood in preparation for a whole winter? Heck, I live in a house with modern heat, not a tent. My suplimental heat is my wood stove. I've already burnt 3 cords of wood this winter! OK, the wife likes it warm. You get the idea.
Are you prepared for the mental challenges of being 'mostly alone' in the wilderness for an extended period? Are you and your buddies good friends now? You might not be when all is said and done.
Not on your list: THE Good Book. (Book of what-ever faith you believe in)
