I'm with Steve--pull the pork, cool, fridge, reheat. The brisket I'd cool and reheat whole were it me.
It's best to cool fairly quickly. The meats can come out now. Unwrap the brisket and stick on a rack in a roasting pan or on a sheet pan and stick on the counter for 30 min or so to begin cooling. (The rack allows for better air circulation.) Save any juices from the foil. After 30 min or so, stick the brisket (still in its rack/pan arrangement) in the fridge, loosely covered, and allow to cool completely.
Meanwhile, remove the pork and unwrap and allow to begin cooling. Pull them as usual, but put the pulled meat shallowly in pans so that it will cool more quickly (chilling the pans in the fridge or freezer ahead of time can help). When possible, put the pans into the fridge, loosely covered, leaving them till the meat is cold. At that point you can, if you wish, combine the meat into one pan for reheating later, and/or package whatever meat you'll not be serving for storage in the freezer.
For reheating, drizzle the brisket with a little of the saved juices, or with stock mixed with a little unsalted melted butter, or with juice, place a remote probe in the brisket, cover the pan tightly, and reheat (@ 300F) to an internal of 145-150. Rest 5 min; slice, serve.
For the pork you'll be serving for dinner, toss with a little juice, as Steve suggests, or a vin-juice combo, or a little sauce, and reheat, tightly covered (also @ 300F). Stir once, well, after about 20 min, and again 10 min or so thereafter, recovering the pan each time. Reheat till hot.
