How many inspections are required?

You mean for a homebuilt? Just one (by the FAA or designee) to get
the airworthiness certificate.

There's no longer any "precover" or other intermediate progress. You are
advised however to get someone (EAA Tech Counselor) to go over your
product from time to time (especially before the structure becomes hidden).
