Loki:

1. Bigberts Citrus Car Shampoo (1 Gallon for only 400 bucks)
2. MF will do, but if you can get your hands on a Waffle Weave, get it.
3. Not necessary

For Waxes:
You can't go wrong with the Mothers line of Waxes, shop around True Value or Hans Tools they carry that brand. After you gain some experience, try other brands mentioned in this thread
