I have a 4.6 lb ham from honey baked hams.

Technically your ham is already cooked. So you could eat it as is. If you want to reheat it and/or glaze it put it in an oven at 350 tightly covered with foil for about 10-15 minutes per pound. If you are going to glaze it yourself remove the foil and spoon on the glaze for the last 10 minutes. Watch that it doesn't burn.
1977 has got it, but I would go in with a lower temp - 275- since you are simply reheating it and not cooking it. Nothing wrong with serving it at room temp either. A nice variety of mustards will be nice too.
But it was delicious! Really!
