There are many shops here. Go see the sea lions at one of the piers, can't think of the exact one off hand, and fight the crowds. Or at least fight them in June. The weather will be a lot cooler than you would think so if you are cold-natured, bring a light jacket.

I'm a native so I pretty much don't visit the tourist spots unless I'm showing company the city. Yet, it's an SF must see. There's been a trend of casualizing the area. The Franciscan used to be a place to dress up to...as was ASabella's which is now an Applebees. Nothing wrong with that, but the area is changing.
This is the place if you want fresh sea food, you are guaranteed and unlimited. There's one place you need to see as well, it's where the cable car dead ends and where it is rotate so it can go back up the hill. The machine is original, where an operator manually has to use his own strength to rotate the turntable with the cable car on it, interesting experience. There's a historical ship exhibit worth checking out and the famous chocolate factory. As a music enthusiast you'll enjoy many live performers along the way.
I generally don't like urban trails, but who could dislike the San Fancisco Bay? I was even sick when I walked this, and I still liked it. The SF waterfront and all the urban and marine scenes made this a truly memorable walk. Remember, if you want to make a side trip to Alcatraz, it is very popular, and the tours require reservations.
