Yes, macroevolution does involve some other concepts but it all comes down to the same process. Mass extinctions also change the allele frequency.

B: Yes, but in this case the change is not due to selection, drift, or (insert other favorite microevolutionary process here) but an eviornmental catastrophe or meteorite impact. The point Stanley and others make, is that you can't make much progress understanding long term trends in evolution simply by stating " change in allele frequency ". Any more than looking at a chemical reaction and say "thats due to QM".
