Welcome to FIRST! I know the feeling -- my team was a rookie team last year. And we actually created a website specifically for this.

Check it out -- it has links to most of the starting documents as well as tutorials for the sections of a typical FIRST team. If you run into problems, post on the Rookie FIRSTs website or on Chief Delphi and there will be tons of teams willing to help you!
