Only if you don't boot the machine again.

If rm -rf has been put into the init sequence (perhaps /etc/boot)
then by starting the machine again the rogue code will be started and do it's damage.

You can boot with knoppix and then mount your partitions and examine them for damage.
Did you install tripwire?

Tripwire looks like a pretty good software! So i still that after booting with knoppix?
I looked into my system and this is what I found and wonder.

Does this show that the email was sent by root?

I think the hack that sends out the email with shadow and passwd listing either has root access or shadow group access. Becuase according to this below it shows that only user of shadow or root can read the file. If the hacker has root, what is the purpose of getting the system config or shadow file via email.. I don't see a reason going through all that trouble. So must be user gdm.
