To me, it sounds like you're all set. You are already ahead of dozens of teams in the US by joining these boards and posting here. You found the right place if you need help with anything. As for the complexity of your robot, over the last couple years the Kit of Parts has really become more of a Kit than just an assortment of supplies. It comes with most everything you need to build a robot that drives. Don't worry about things like 2 speed transmissions, just entering the competition is a huge accomplishment and making a robot that moves is an even greater accomplishment.
