You get it all off the same vendor, What you want to do, is head to Corrahn's Dagger, it's north of Southshore, it's a cliff, easiest way to get there would be to take the path that's beside Tarrenmill and go north untill you see the mountains, don't go past them, just follow them west, untill you find a camp with alliance, you'll find the vendor there among the NPC's
