Living Conditions is fantastic (don't forget the sequel Everything and More).
As I remember it the first fic is LA based then they are back in Sunnydale for the sequel with some Angel issues included...

Paradise Lost by Belladonnaroses
They meet in LA, hoorah! but then part ways, the sequel has Spike return to SD though but I can't remember on the scooby angst side, angel isn't around.
Unsuffer Me by enigmaticblue sequel
Certain Dark ThingsSet between BtVS S2 and S3. A chance meeting leads to an unexpected connection.They went off together to LA in this, but Buffy returns to SD and it roughly follows the show but there isn't acceptance from the gang so that might meet your angst requirements!!
Half Way to Anywhere by immram
What if Becoming ended a little differently? What if Buffy and Spike had been friends ever since thier tentative truce? Would things have worked out differently? This is my attempt to find out!They meet in LA at the start of this series but I don't think there is much angst/opposition as far as I remember.
