After you do the quest about boone's wife and I recruit him is there another quest for him? If so how do I trigger it?

Yes, the triggers to continue on Boone's quest involves killing members of the legion.

What if I already did those things with raul? When I dismiss raul and get boone am I pretty much out of luck now?

Anyone?
