1. San Francisco, as a city, isn't that big. I don't think its worth focusing on having to be in one particular area of it, simply because everyone else is. You don't have to worry about traveling to/from the city until you're in Berkeley or Mountain View or elsewhere in the bay area. Worst case, you take a cab. And I can't think of a scenario where it would cost over $20 (tip included) to go somewhere within the city by cab.
I spent the summer in the Bernal Heights area,(pretty close to the southern edge of the city - just south of the Mission). Its somewhat far away from SoMA (30-45m by muni + bart -- made this trip daily to go into the office, its not that bad). I've really never had any problems getting around the city whenever I need to go somewhere.
2. It'll take more than a weekend to find a place, but likely less than a month. I'd suggest to sublet for a month, but, no reason why you can't use AirBnB or something similar on a weekly basis.
3. Most of the events/meetups I follow are for iPhone/Mac dev-type things, not marketing (which seems to be your area of interest). So I can't help you there, sorry. But, if that is your cup of tea, there's weekly NSCoder night, an iOS Dev Camp coming up in a few weeks, and so on. Github has one, the Cappuccino folks do, etc. Lots of stuff going on.
4. There's no such thing as a weekly muni/bart pass. Maybe its because I'm used to NYC where the MTA has these, but, this really surprised me.
BART has no passes, but if you pay $10 extra for a monthly Muni pass, it'll work on BART within the city (only). That's what I did before I decided the mission was too grim'n'gritty.
To the original poster: Muni buses are notoriously unpredictable, as in sometimes they just don't show up and the next one is filled to capacity. Muni trains are pretty reliable (except for some complaints that the N-Judah can turn back before the outer sunset), and BART runs like clockwork (off grade FTW).
I do marketing for a living but I'm also pretty technical, so tech/startup events are definitely something I'm interested in. Something like Hackers and Founders would be exactly what I'm looking for.
