Camp food! Questions, comments, tips?

We are visiting Yellowstone on our National Parks road trip. As an old Boy Scout at heart, I'm over preparing, (no such thing?) and wanted some advice on what to bring for camp food and supplies. We are staying at the Madison campground in a tent for 3 nights. I figured dehydrated food and canned food would be the easiest to transport. So anything that can be cooked on a small camping stove. A few pans and pots and utensils. As a Midwestern flatlander, I never had to deal with bears, any tips with food storage and keeping them from getting too close.
