Hello, Dunk.
Ned's suggestion to smoke Pork Butts for pulled pork is good advice. IMO it is the best solution for feeding large groups a smoked meal. First, butts are very forgiving cuts of meat. And pulled pork reheats very easily and well, so you could smoke and pull the pork ahead of time, then just reheat the day of your gathering. Use the search window at the top of the page to browse "pulled pork" or "butts", and you'll get many threads and posts with great info on prepping, cooking, pulling, resting, storing, etc.
BTW, it looks like this is your first post. When you have the chance, stop by the Roll Call Forum and tell everyone a little about yourself. It will give members the opportunity to give you a proper SMF welcome.
Good luck, and let us know how it turns out.
