While you're at Wally-World getting your tent look for a cheap carpet/rug. Assuming you're car camping the weight of a small rug won't affect you and having a small rug in front of the tent entrance helps a great deal to keep the dirt/mud/schwag out of your tent.
Also at WW you can get a small "grill basket". You know, those small metal baskets that lock closed. They're awesome for cooking vegies or almost anything over the fire.
Bring a bucket for washing up dishes and yourself.
Rope, duct tape, zip ties along w/ other things folks have mentioned.
