If it were me, I'd probably heat the precooked ham at 350º for about an hour. That'd be my best guess if I didn't have the instructions from the wrapper.

well, to cook a PREcooked ham you have to sit on the ham for atleast 3 days and 47 minutes although it may help if you fertilise the ham with your natural feaces, or juices (yes that includes sperm) every 15 minutes.
How long do I cook a precooked ham? It is 15 lbs. A precooked ham does not have to be cooked, but will taste better if you heat it thoroughly to an internal temperature of 140°F (60°C) or so. Place the ham in a 325°F oven (163°C). It will take 12 to 15 minutes per pound for a whole or boneless ham and 18 to 20 minutes per pound for a half ham.
