Going to get started

I've been reading this group for years. I am ready after much thought to
take the plunge and order a kit. I have settled on the Van's RV-7A. My
question is can anyone point me to a summary of how to get started. I'm not
talking about building or anything like that. I mean the paperwork aspect.
I would assume that early on the FAA should know of my project to monitor
it. Who do I contact. Will Van's help with this aspect? Is there anywhere
a good summary of the FAA rules and regulations. Although I have spent
years looking for the right plane, I haven't spent any time looking into the
paperwork and regulatory aspects. Ant input would be appreciated.

Thanks

Barry
