Most of my contacts are associated with one or more categories, which

Is there a way to automatically add (and remove) contacts with a
given category to a distribution list enmass rather than
individually. Some of the lists have 100 + contacts.

Display your Contacts in the By Category view. Select the contacts you want
to change, then drag the selection to the category you want them to have.
