Yes. The requirement is so prevalent that it's seldom explicitly mentions.

Always. This tutorial discusses why it is needed, choosing appropriate
values, and different types of noise management and isolation:

Never useless.

Generally a canned oscillator will have a ground lead. So it's not
necessary so add an additional one.
