You can probably still use the notes; just take them to Ranger Jackson at the Mojave Outpost. In my tests, you could kill one of the targets and still finish the quest via the "peaceful" option. Hey, leaving one out of two of the people who tried to kill you alive counts as peaceful, right? Once you kill McLafferty, though, the quest is over.
As for Jean-Baptiste not being searchable, I don't know. I could search him, but you're not the only person who's reported the same thing. Have you tried moving his body to another location? Maybe he's just blocked by some debris or something.
