The one you are taking to work, you could leave it whole and heat it up in the oven at home and hold it in a cooler until you are ready to serve. How long will is from the time you leave for work until lunch?
The second one, I would leave it wrapped and put it in the fridge. You will not lose that much moisture. Reheat at about 300*F until 160*F(for safety's sake). Heating at the high temp will get the meat to temp faster and not give it a chance to dry out.
