No longer a newbie, but still clueless.
Is that bone-in? If so, it's done when you can wiggle that bone, or 195-200. As IB said, I'll usually start 'em so I have plenty of time to cook. Then double wrap in heavy duty foil (two layers) and a towel, then throw it in a cooler. It'll stay hot for a few hours at least.
