I wouldn't worry too much about the mold. I mean, if you expose, say, 20% of the mold in the patch you do fix, then there is still a bunch back there, and if they have access to moisture, they'll continue to live there.
Undisturbed, they're not much of a health hazard in the wall cavaties. But when I do run into it, usually treat it with some diluted bleach (spray and let dry couple times) and then top with spray can Killz
