For the Muni transportation such as streetcars (F Line), buses, train-like things (J Line) we just pay daily (.75, have correct change) for ride with 2-4 hour transfer. Even though you can ride with an expired transfer, there are occasional Muni police checks of transfers and scofflaws have to pay a fine. SFMTA has details (see link below) For BART, there are several places to buy senior passes. See their website for where.
There is a multi-day, multi-attraction pass from SFMTA (I think) that's probably a good idea for first-time visitors.
Here are my thoughts on budget travel in SF: http://ckjournal.blogspot.com/2012/06/thoughts-on-budget-travel-in-san.html - lots more on transpo, links to maps, etc.
Have a good trip.
