What I've got in /etc/mail/spamassassin/local.cf is

 # Add mydomain.com to white list.  Note that this will allow mail FORGED
 #  from mydomain to pass through.

 whitelist_from *@mydomain.com
 whitelist_from *.mydomain.com

My reading of perldoc Mail::SpamAssassin::Conf leads me to suspect that
both of those lines are needed.  I didn't test with just the second one.

According to the SpamAssassin docs yes.  Note that there is an
"unwhitelist_from" and "unblacklist_from".

According to the documentation, yes.

This I don't really know.  I'm still not entirely clear how these whole
things in invoked so that there isn't massive perl startup overhead with
each message.  Since I'm not clear on how that magic works, I'll leave it
to others to answer that question.

You posted that to a mailing list.  I'll keep this one in mind the next
time I add to
