You're asking for a summary as well as a listing.  You'll need two queries.
One to get the member_id for the top 25 referers, another to pull the
information for those members.  You can use ...WHERE member_id IN (list)
on the second query, where "list" is a comma separated list of the member_id
values.  Probably best to put this stuff in a Perl script or something so
that you can manipulate the list and construct the queries easily.
