Danny,
That's too much for the #2, at one time. Two butts is almost too much, depending on the size of them. I recommend doing the 2 butts separately, and then double-wrap in foil & refrigerate (whole, in the foil). Then, do the ribs on the day they're needed. Start them no later than 11 am, then double-wrap them, when done, and head to church.
While the ribs are smoking, place the wrapped butts in a crock pot, on low, for 3-4 hours. If you don't have a crock pot, set your oven on the lowest temp, and heat them for a few hours.
When the ribs are done, and the butts are hot, place all of them in a cooler (or 2), with towels above and below. Transport them to the church, and get ready to serve. Take a large disposable aluminum pan (like a turkey pan) to pull the pork in. The ribs will be a simple unwrap and slice. It should all be hot, if you do it like this. Reheated pork butts are great, if you heat them whole, then pull them when hot!
Bet you'll win the competition!
