How should I prepare this smoked ham?
Hams are either ready-to-eat or not, thus spoke the USDA. And, by its regulations, a ham that must be cooked has to show cooking and safe handling instructions. 


  Hams that are not ready-to-eat, but have the appearance of ready-to-eat products, will bear a prominent statement on the principal display panel (label) indicating the product needs cooking, e.g., "cook thoroughly." In addition, the label must bear cooking directions


The 'cured with' portion tells you that you have a wet-cured ham, one that was either injected or soaked in a solution of water and salt, sugar, etc. According to the label, it was smoked after curing.

Yes, you can keep it in the freezer, frozen; in the refrigerator section, it will gradually come to the same temperature as that area, which is how you would want to thaw before use. It will slice like other proteins, such as chicken or beef, using a regular knife. It is ready to consume, sliced, diced, or chopped into a ham salad. It can be fried up as a breakfast steak or heated, either as is, or glazed and oven-baked to 140°F internal temperature (safe because it is cured and pre-cooked).
