I would add the Japanese Tea Gardens in Golden Gate Park, and the San Francisco Museum of Modern Art (especially if you're a yahoo), but otherwise this looks like a great list!

you can skip seventeen mile drive. it is totally overrated. friends raved about it...friends who hadn't been there in over 10 years. so i went. unfortunately, it was nothing like i was expecting--i didn't mind paying the $8.25 to the park service (i support our parks), but when it turned into a home tour, i couldn't wait to get off the 17-mile drive; that's not what i thought i was paying for. it was only when i finally emerged at the ocean that the scenery paid off--saw a couple of sea otters frolicking in the kelp. you can see all the best parts of 17-mile drive driving south from monterey (from the aquarium actually). it's also crowded...so if you're looking for beautiful coastal scenery without the crowds, take an extra day and head into the heart of big sur.
