Inject that bird with one of these: http://www.butcherbbq.com/#!bird-booster or similar, we did 5 pulled turkeys for a wedding a couple weeks ago and people loved it. You can always add chicken broth while holding or reheating for moisture.
On the kettle I'd put the legs towards the heat. As for temp, I usually shoot for 325 to 350° too
Greg thanks for your input, that's what I had in mind. Did you do yours on a kettle(s) or smoker(s). I'd love to hear more about what you did.
