I've been reading some of the FAA documents and am sort of confused about
something.

I don't see any requirements for a pilots license when applying for
registration and such for a homebuilt. is it implied that you already have a
license or is none required?

I see talk about reserving your N number then getting inspected, then
getting your 25 (or 40) hour permission.

note: I am talking about what's required, not what is heavily recommended.
