The points mentioned are good ones. You may also want to continue in this area to the Point Bonita Lighthouse for a good view.
I suggest that you go to Crissy Field, park, and walk along the promenade to the Ft Point area, and from there (At the Warming Hut) you can climb up a set of stairs to the Golden Gate Bridge, and then walk across the bridge. Another spot for a good aerial view of the city is from the top floor of the deYoung art museum in Golden Gate Park (you do not need to pay entry to the museum to visit the top floor). Oh, also the Japanese Tea Garden nearby is nice.
Enjoy your visit!
