HAMZILLA in the making!!

[Tenpoint5]

In the 10-12 pound range what cut, specifically should I request from my butcher?  Boned?

You want a fresh ham.

FLB has you covered. You want a Fresh Ham/ or a it is sometimes called a Green Ham. Boned or not is up to you. You will probably pay  more for a boneless. Bone in is good because then you have a Ham bone to make some beans or ham and bean soup. If possible I would suggest getting a skinless ham, saves you the hassle of taking that off. Unless your wanting to hit it with a little smoke slice and deep fry for cracklins
