Outdoor Life

They're good, but your first time camping you may find you don't enjoy it. Rent or borrow a tent, or buy a cheap new or used one.
A pad on a cot makes it a little more comfortable, but it's not 100% necessary. Sleeping on the ground you need a pad as a minimum, an air bed is better.
Good food to share is fruits, nuts, popcorn, cheese and crackers...any kind of nibbly stuff. Bring plenty of water. Handi-wipes are good too, you can even use them for a crude shower if no facilities.
Anything you can boil water in is fine for making tea. A teapot is the handiest. You'll need an oven mitt. If someone else is doing cooking, you don't need to buy a camping cookset. They aren't even useful anyway (too small, too flimsy, and tend to burn food). Much better is cast iron skillet and Dutch oven (which are also useful at home). But wait and see if you like camping first.
eta: one more tip. Whether cooking over a fire or camp stove, the bottom of the pans will get really sooty. Rub a bar of soap on the bottom and lower sides. Not the insides of course. That will make scrubbing the soot off much easier.
