Welcome! and nice job! Best advice... "search" and read. Everything us newbs want to ask has just about already been asked. I found everything I needed to know last year and just applying the basics of what everyone here is doing made it possible for my 2 kids to literally slay the pack at our Awana Grand Prix. Definitely look at DerbyDad4Hire's page as I second what Chalk said and check out 5KidsRacing page also. Video's on 5Kids are great. DD4H's products are stellar. This will give you the edge you need to go very far if not all the way.
Regards,
Jimmy
