For just starting out I would say:
4 polishing pads, 3 finishing pads.
Lots of microfiber towels
clay bar
cleaner polish(es)
glaze
synthetic wax/ sealant
carnauba wax

Choosing those is really an opinion type thing.. Just try to stick with the products you pick, and get used to how each one works.
Technique is more important than product, remember that.

Also, I honestly recommend the Meguiars pads over the LC pads. A lot of folks think the LC pads are a little better, but I think its much easier to pick between 2 pads (can't use cutting pad with a DA) than 5 or 6.
That's all up to you though.. Good luck!

One more thing- The key to using the DA is PATIENCE!!!! It's a great little machine and can accomplish many things, but it won't do it overnight. Don't get frustrated if you aren't getting the results you want at first. Take a break, try to figure out the problem, and give it another go.
