IIRC Pathfinder will be dumping LAs in the system. With the PHB races slightly bumped in power the Tiefling and Aasimar can probably be used more or less as is from 3.5e sources (Races of Destiny). Though I imagine the Bestiary will have these planetouched out in Sept with adjusted stats to bring them more uniformly in line with the PHB races. Same should go for the dragonborn most likely, Races of the Dragon might be a good place to look.
