If they're not enhanced, I'd brine them. It's not entirely necessary, but gives you a little leeway of you overcook them slightly. Those should be good to go with a 12 hour brine. If you want the skin to be more palatable you can also leave them uncovered in the fridge for 18-24 hours.
Cliff's time and temp estimates look fine. I do mine a little higher (325˚-375˚) and pull them at 160˚ to let carryover take them the last 5-10 degrees, but that's just my preference.
