Is it even plausible that, with the proper information and necessary equipment, let's say from AQ's apparent connections to Pakistan's Khan and/or at least some of the scientist's working for Khan, that they (AQ) "could" maintain the viability of these weapons for an indefinite length of time if they were still operable at the time of purchase?

Nope. Tritium decays, plutonium decays, and Pakistan doesn't have very much of either to hand out to terrorists.

If AQ knowingly bought the weapons in an inoperable state, is it plausible they could be "refurbished", for lack of a better term, with the proper guidance and materials, or would it be more likely they bought them knowing the most they could do with them is construct a "dirty bomb".

The latter.
