For the ssh stuff, a sane sshd install (including the one that comes
with SUSE) will generate host keys if they're missing. If you look at
/etc/init.d/sshd, you'll see "if -f" tests for all the keys when
starting. So after step 7, once you've started the machine up with the
new host name, you should be able to (as root):

/etc/init.d/sshd stop
rm /etc/ssh/ssh_host*key*
/etc/init.d/sshd start

As a bonus, this way each system has a different key.
