Thanks for the advice so far! As far as location, I'm a little schizo right now as I am debating between being close to work vs. living in an area I really like.
Last summer, I lived up from the Mission Dolores and absolutely loved it. Convenient since all the MUNI lines come together there at Church, a fairly short commute to work, the Safeway was right there, and I was w/in walking distance of some great areas. Definitely considering living around there again.
I think I'm going to take about a week and check out places using multiple sources.
