I wouldn't worry about cooking if you don't have any experience with it at a campsite. Get a cooler, put sandwich making stuff in it and drinks. Call it good.
This isn't survival camping, as Rob said, you can go into town for every meal if you want.
Big things are to make sure you will be warm and dry when you sleep. Tent, sleeping bag, cot/air mattress.
Everything else can be dealt with.
