The ganache will go bad long before the nuts turn rancid. I think you can figure about 3 weeks for your truffles until they spoil, grow mold, etc. unless you freeze them. I am assuming you know your nuts need to be toasted prior to using them with your chocolates. Doing this accomplishes a few things but should also extend the time before they turn rancid. I've found old bags of untoastednuts in the back of my cabinets after monthsand they seem fine. How quickly they turn rancid will depend on the oil content (plus storage conditions).

I would never cover anything in nuts.... The point of roasted nuts is the ::crunch:: which in combination with chocolate is sublime. Within a day the truffles will be covered in soft nuts .... Just my opinion.
