A couple other things:
1. You can rent a car at 21, but it might cost more than if you're 25 or older.
2. Use AirBnB to book rooms. Usually cheaper than a hotel and better accommodations.
3. Use Yelp (website/smartphone app) to find good places to eat.
4. The weather in California doesn't vary a lot. San Fran is cool/foggy most of the time, but can clear up nicely on some days. Feb/Mar is the rainy season, so expect to get a bit wet.
5. I don't think there are too many cultural oddities you need to worry about. SF in particular is a pretty international/cosmopolitan city. Just don't be a dumbass and you should be fine.
Have fun. America is huge and gorgeous and generally a pretty rad place to be.
