I have the following paragraph in my "Degrees of Freedom" story. Is it formated correctly?

"I had to tell one student that anything on 3D was not a classic. So he based his story on an old 2D TV show. He made this starship captain gay so he chased the men instead of the women. Another made Moby Dick a horse. '...whoever of ye raises me that same white horse, he shall have that gold ounce, my boys.'" Reg downed his drink and called for another round.

The question is, at the end of the dialog, is it correct as above or should it be ...my boys'."

Is there a good book on punctuating dialog? Does anyone want to write a guide for this forum? I have a few stories with unusual dialog constructions that I would be happy to donate as examples.
