Always keep a rescue disk around. Never work on the system as root, only if
it is really necessary. A normal user can't crash the system (well, he
shouldn't be able to do it at least).
There is nothing and nobody that or who prevents you from crashing the
system. If you log in as root, the system trusts you and do what you want.
You are god if you are root.
Never switch off the computer, even when it seems to be stuck. ESPECIALLY if
it stucks while e2fsck is running... I had a bad experience...

Just installing a new package shouldn't mess your system (at least packages
from the stable distribution). If they do, it is a serious bug. But if you
configure your system in a different way, again, nothing will prevent you
from messing things up.

Shadow password should not give you any problems. I never had problems with
shadow password, they are really the default today in the Linux world.

It is not only to hide secret data. If a cracker can login into your system,
he can try to crack different systems from this account, hiding his actions.
It would appear as if a user from your office is doing the crack. So you
definitely want safe your system, especially if it is connected to the
internet.
Thank you,
