It depends. If the configured values for DEFAULT_URL_HOST and
DEFAULT_EMAIL_HOST in Defaults.py are correct, you don't need any
add_virtualhost() or VIRTUAL_HOSTS.clear() directives in mm_cfg.py.

If you need to change these or if you just want the settings in
mm_cfg.py for documentation purposes, put


in mm_cfg.py. Note that you must have one VIRTUAL_HOSTS entry for
DEFAULT_URL_HOST and DEFAULT_EMAIL_HOST. This is added in Defaults.py,
but may not be the correct names. The purpose of VIRTUAL_HOSTS.clear()
in mm_cfg.py is to remove the possibly erroneous entry added in
Defaults.py. It isn't really necessary to do this in any case, but
it's cleaner.

>Furthermore, I am aware that once configured for virtual domains, mailman automatically generates certain files: /usr/local/mailman/data/virtual_mailman, among others. However, it is not clear to me whether these files will automatically be removed or whether their removal requires my intervention. Indeed I don't even know that they would need to be removed. 

They won't be removed, and they don't need to be, but the reference to
data/virtual-mailman in Postfix virtual_alias_maps needs to be removed.

>Finally, there is bound to be more to this than I merely anticipate. Perhaps there are other files to modify or remove. 

Probably not.
