Not knowing what the charger is that comes in the rookie kits these days, I would definitely get another one (I think there's been discussion on CD of various types of chargers and charge rates--a CD search should turn up those threads).

Batteries: You'll get 2, as a rookie; the Manual will tell you what the accepted additional batteries are. They'll be 12V motorcycle batteries, unless something changes. Get 2-4 extras, and consider getting a battery tester, if not this year then soon, to verify that they're working properly. Then set up a battery management system so you know that you've got a good battery every match.

Oh, there is one other place you will want to get VERY familiar with. http://www.andymark.com/ These guys sell motors, gearboxes, chassis systems, batteries... They are also, to some extent, FIRST's "surplus" or "outlet" for game pieces if those aren't readily available, and for the FIRST Choice kit additions. Got an extra couple thousand dollars lying around? Get a complete chassis and build a practice drivebase. Need mentoring? Though that is better done locally, Andy and Mark are both experienced mentors. Can't find assembly instructions for the KOP gearbox? They'll be on that site. Quality is excellent, and customer service is outstanding.
