Curing time?

how long do you leave the clear coat to cure?some people say 1-2 months but on the stew mac site he says you can begin wetsanding in a week?

It really depends on what you're shooting. Catalyzed urethane can be sanded the next day, nitro should be 4 - 6 weeks. Acrylic lacquer can be sanded in less time. With lacquer, the longer you wait, the better.
