Hey!
I Lived in SF for about 8 years, so I have been down that road.
If you are strictly talking Marin for Stripers, I would use plugs/cranks, and especially the local favorite, Hair raisers in the Bay shoreline, Napa, and Petaluma Rivers when they are running. (Basically a Bucktail jig with a grub on the hook) White, White/ yellow, White/chartreuse, and White/ red are the most popular colors.
I LOVED fishing the entire Marin coast both in the Bay and the Pacific, but the bay is your best bet for specifically stripers, SF Beaches and south to Pacifica, the East Bay, etc... are the place to be sometimes... just depends on where they are in the run, of course. PM me if you have specific questions... I could go on and on about CA fishing...
You should definitely check out the Web Site and forums for Pier Fishing in California... awesome resource.
Created by Ken Jones, the author of the book Pier Fishing in California, now in I believe its 3rd Edition. I strongly recommend buying and reading that too.
