In the tradition of whole hog cooks, I would probably just baste, slow roast over coals (no Smokefire option there) for a long long time, and baste some more and more and more....
It's pork...actually really tough to overcook - particularly when it's on the bone and larger cuts/mass. Longer, slower...pretty hard to mess it up really. It will drip a lot of fat...so don't let a flare up scorch things...maybe higher up and a good drip tray? I have not used a Smokefire so limited knowledge there.
