I deal with bacteria at work from time to time, and unfortunately,
microwaves are not really useful as a sterilizing agent. They only kill
microorganisms by heating, not by causing direct damage to the bacterial
cells the way that, say, gamma rays would. So, microwaving is no more
effective for killing bacterial spores than direct heating would be. In
fact, it is likely to be less effective, because microwave ovens usually
leave cold spots.

Almost certainly. If you get hot enough to kill AFB spores, you are
well up into carmelization temperatures. Reliably killing bacterial
spores with heat requires an autoclave (about 125 deg. C, or about 260
deg. F) for at least 10 minutes.
