Replying to Road Tripping Down the 101

So in about 3 weeks I'm going to be driving from Seattle down to San Francisco, sticking mainly to the coast. Looking for local suggestions on sweet places to stop. Open to pretty much anything from cool beaches, parks, museums, vineyards, and towns worth checking out/wandering around. Also, if anyone knows of good camping in the Mendocino and Napa areas, that would be greatly appreciated. As would any cliff jumping spots anywhere along US 101. Thanks, yo!
