OTOH, an ordinary noise attenuating headset loses effectiveness when
you stick eyeglass (or sunglass) temple pieces between your head and
the ear cushion. The bump around the temple pieces allows noise to
leak in. Years ago, David Clark sold little foam wedges that slipped
on your eyeglasses to smooth over that gap. They worked well, but
apparently they're no longer available. Does ANR eliminate the need
for such accessories?

Yes.

(I've owned six pair of ANR headsets...and I wear glasses.)

BTW: I've not been able to justify spending $1K on Bose headsets. I've been
with Lightspeeds almost since they started, and can testify that they have
solved their early problems with durability. They have features that Bose
simply does not offer (built-in cellphone/MP3 interface) , and they stand
behind their product like no other company I've ever seen.
