Yes, the chops come from your backstrap. Chops were always my favorite until our butcher went out of business and my dad and I started butchering our own, now we just keep the straps whole.
My favorite way to prepare chops is to marinate them overnight in Italian dressing (after soaking them overnight in canning salt water), and charcoal grill them with mesquite or hickory chips. I charcoal grill all of my meat unless it's a part of a recipe.
