Great. Welcome to FIRST. There is a wealth of information to be found here on Chief Delphi and at the NEMO site.
http://www.firstnemo.org/
NEMO will guide you through all the non-technical stuff you have to do.
I would also contact FIRST at
frcteams@usfirst.org to find out who is in charge in your area. Get in touch with them. They love new teams.
Good Luck!!
