I've met a lot of great coaches during my years in FLL, and they rely on each other for advice (for example, this email list) and other resources.
Don't forget about the Coach/Team Resources page on the FLL website: http://www.firstlegoleague.org/challenge/teamresources
-- There's a series of phone calls scheduled (with recordings and slides) talking about different parts of FLL
-- There's a list of great links to help you learn about building, programming, and controlling robots
-- There's a section on how to tackle the FLL project
-- There are links to other great resources, too.
The Virginia/DC FLL website at http://vadcfll.org also has lists of team resources, as well as information about tournaments in VA and DC, and the handful of policies that describe tournaments in our area.
====================================
FLL is great fun for team members, and even for coaches and team parents--it's wonderful how much the team members learn and are able to do over the course of a season.
[By the way, tournament volunteers have lots of fun, too, and it's a great way to get insight about how other great teams work. You can volunteer for a tournament at the VADCFLL.ORG website, or by contacting a tournament director.]
