Sounds good so far.

ezmlm is a particularly nice way to go, because of its completely automatic
bounce handling.
If you don't want to do that, write a little script to pull the recipients
out of the database and inject using /var/qmail/bin/qmail-queue. You'll
need to read the man page for qmail-queue to figure out how it wants to
be called.

This won't buy you a lot, providing your qmail installation is logging with
multilog. And not logging the sending of 60,000 messages is not a bright
thing to do for a mail administrator.

Your fd limits will need to be set high.

tcpserver doesn't affect outgoing mail at all.

Yes, you could. It will still have some effect, though, because they will
be sharing I/O bandwidth on the queue and log disks, and on the network.
