You can get everything you need at walmart actually. Everything they have is cheap, just avoid anything that says Armor All or Turtle Wax on it. When you are at Walmart, pick up anything that says meguiars, I know they have polish, wheel cleaner, tire dressing, and wax. All of these are fantastic products. If you cant find meguiars wax, try Zymol (it is a light blue color and is $12) and it gives the car an unbelivable shine.
There are also lots of drying products there, you can try a chamois if you want or they have towels made for drying cars, those work too.
