Yes, the hand was used to clone Luke, and the lightsaber was given to the clone, Luuke, after Luke defeated him he gave it to Mara Jade (an Emperor's Hand) who had been tasked to kill Luke by the dying Emperor via some fomr of remote Force communication. Worked out in the end though, Mara and Luke get married down the line.
