You HAVE to go to Angel Island and Alcatrazz, and if you want to do it, you need to book the tickets online NOW. You may already be too late. Once you've done that, a walk on the wharf to see things like the musem of arcade machines, the submarine, etc, is a must. You can also go over the bridge, obviously, and if you do, and then turn left to go to the upper car park, the view is awesome. There's a wharf that has a lot of pontoons with seals on it, and an aquarium. The restaurant on the upper deck that has views of Alcatrazz is brilliant, but not cheap. That whole area is good for buying gifts. There's several places on the wharves that sell home made huge chocolate truffles, they are always a good deal. You should try to get to the museum that's all about the trams, and you should try to catch the trams, too. A bit outside SF is a computing museum that is beyond awesome. They had a Babbage Analytical Engine running when I was there, one of only two in the world.
