I have been camping for a very long time. Here's some tips:
Get a good tent - one that will give you plenty of room - our last tent was a 3 room but we didn't put the room dividers up, we just left it open. Make sure you also waterproof the seams to help when it rains and leakage. Also remember that you shouldn't let anything touch the sides as that will spawn leakage. Also get good metal stakes. Usually the stakes that come with the tents are plastic and break easily. Also make sure you get a mallot to help put the stakes in - it saves your feet some pain!!!!
If you go someplace that has electricity and it's hot, don't be afraid to take a fan to run in your tent. Make sure you have an extension cord that is for use outside (of course you have to keep the plug in end from the fan to the cord inside the tent.
Make sure you get a water jug to have for handwashing.
Campstove - Coleman is a great company. This will be needed to help cook and to heat water to do dishes if you have any to do. You can also do this over the fire but I didn't like doing a fire in the morning and then again at night.
Tarp for under the tent - this will help keep the moisture out of the tent if it rains.
Mattress for under your sleeping bag - nuff said

(If you don't want to go to the expense of sleeping bags, and you are mainly going to camp in the summertime, just use some old sheets and comforters from home. That's what we have used.
Get a screen tent - this will allow to be under some cover if it rains. You can either put your picnic table under it or your lawn chairs. This will also help with bugs. We played cards and games when it was raining under the screen tent. If it rains sideways and you get wet under the screen tent, head for your tent and tell stories or read.
Make sure you have at least one lantern for at night and some good flashlights for the night to walk to the bathrooms or just have fun with. Take a few rolls of toilet paper to have on hand for the bathrooms in case they run out; we've had that happen to us.
Get firestarters and have some newspaper to help light your campfire. And during your campfire - sit back, relax, and enjoy. Another great bonding time.
Make sure that at night you either put your food in your car or you put something very heavy on top of your cooler or box that you have your dry food in. The raccoons will get into them if you don't and they have a good tendancy of taking ALL your food they can get opened.
Rubbermaid totes can be your best friends!!!!!
These are some great things you can put on christmas lists. We got a good portion of our camping equipment when we got married because we put it on our gift registry. It was great.
Have fun - take cards and some games. This is a great bonding time. We have not gone further than about 20 minutes away while tent camping. Now that we have a camper and have broken it in (we just got it in July) we will probably try to go a little further next year. One nice thing about being close to home is you can run home if you forgot something.
I love to camp. I can't find a better way to relax.
