I am driving from San Francisco to Seattle for the first time. Suggestions on where to camp or what to see?

My husband and I are driving up the Pacific Coast from San Francisco to Seattle. Neither of us have been. We both love camping and I really want to see the redwood trees and the Hoh Rainforest in Oregon. We plan on eating at hole in the wall places and camping/hiking. etc. Also, the husband wants to surf. Any suggestions on any of this would be awesome. Thanks!
