Next Movie Release from Juve: T.O Race Scene?

Ok, now that I'm addicted to filming, I'm debuting my next film release. I'm actually going to try and do this a bit proffesional.
What I'm thinking about doing is a documentary of the race scene in T.O. Going to the local races, and meets and filming select cars. In the process also doing interviews with some people who are there. I want to make this big, and my only couple of problems are that I'm still not that good at recording, meaning my arm shakes a bit, and how will I go from scene to scene of each car. So far, every "tuned" car that I see I press record, do a circle around it, and then pause. I also **** around with zoom in zoom out, so sometimes it gets blurry. I want this to be as proffesional as possible.

Any ideas HOW I should film this? I mean, just short clips that end and the next one starts, with music in the background during that, and then during interviews, there is no music.
Would this be a cool video to watch? Is anyone interested? I sure as hell am because I'm beginning to love this! But if no one is interested, and I get no help from anyone at all, it'll be a little stupid and hard to do.

Any suggestions welcome!

P.S I forgot to mention I want to do it in a somewhat documentary style!
