Yup, you need to speak to Una in TB.
As far as leatherworking path goes, I'm a shaman and have 254 LW and still haven't chosen a path. Tribal has some nice stuff but, as a shaman, you'll be wearing mail, so probably wont get a lot of use out of it yourself. Dragonscale may be your best bet, but I hear that it's a pain to get the scales.
