Hi Peter, we are just wrapping up a 6 week road trip From Colorado out to and down the Central and Southern Coast of California. We are very avid cyclist's so did a ton of road riding along the way.
If you do not have a Strava account I'd suggest getting a free one. You can then use the free search function for the town you are visiting and look at the maps.
San Francisco: Rapha Cycles- They have group rides but also if you swing by the store they have free cue sheets for all the rides they do.

We stayed at the San Francisco RV Resort. It's about 15 minutes South of the City in Pacifica. It's "OK", the location is great but the facility itself I'd give maybe a 6 or 7. Next time we are going to look at Campgrounds North of the City.

Camping we stayed at the Santa Cruz Harbor RV Park. It's a pretty small RV park, nothing special but in a great location.
We also did a few nights at the Constanoa RV resort just North of Santa Cruz. Wonderful Campground and great riding in either direction on US 1. Hit the US1 Brewery nearby if you like beer.
Monterey: Stayed at the Monterey County Fairgrounds.
17 mile drive is a must bike of course! Did 2 great rides there

San Luis Abospo- Stayed at Avila Beach, great spot but first come first serve.

Pismo Beach- This is the only camping we did with no hook ups. It's at the Oceano Dunes OHV area and you just drive out on the beach and camp where you want for $10/night. I'd suggest this on weekdays, weekends get crazy.
Carpinteria, Stayed at Carpenteria State Beach. Great Spot!
