your criteria look reasonable. A couple suggestions:

- switch to key based ssh authentication, which will allow you to limit
access easily to a given IP block.
- you have to monitor your logs for brute forcing.

my favorite root password generator:

head -c100  /dev/random | uuencode -m -

now just copy/past a substring...

BTW: Make sure that you use a password cipher that supports >8 char
