Rob,
Next time you do a chuck roll, pull it all before refridgerating it. Makes things simpler. As for reheating, you might consider a lite spray of Apple juice and heating it in the microwave at 50% power, 1 min at a time until it's hot enough for you.
You cooked it low and slow, reheating is the same.
