I'm new to modelling as well with only one model beneath my belt. I can tell you this. Read the "Important" threads at the top and don't hesitate to ask questions. Jay (jay@af), Dan (Guiddy) and Warren (Primera Man) are some our most prolific members. Guiddy, I believe, is doing that Calsonic kit, you should ask him about specific questions. Hope that helps!
Here are some general things I've picked up:
Take it slow. Modelling is not one of those things that you can do quickly.
It can be expensive, but the result (in my opinion) is well worth it.
Many things are dangerous (fumes, hobby knifes) (I've had my own painful experiences with the hobby knifes! D'oh!)
Enjoy yourself and make sure that the model doesn't get the better of you.
