If you have a car drive up to the top of twin peaks and get a view of the whole bay area. Than drive west headed out to the beach, on your way stop at Stern Grove:

Continue out to the beach and check out the Majesty of the Pacific loop back around through Pacific Heights headed towards North Beach. I would stay away from Fishermans Wharf. Its mostly generica tourist shops. Unless you want to check out (and smell) the seals or want to see Alcatraz there is no reason to be there. If you like to check out neighborhoods and people watch the best to walk our The Haight and Mission. You will end up in the Mission anyway if you are going to go to the Kink thing. If you are really feeling adventurous I would get out of the city and go up to Sonoma and do some wine tasting. Its about an hour and change away but well worth the trip.
