There is no way to hide the IP of your machine. Unless your using a proxy you can hide your IP to say websites or other servers depends on what the proxy supports. But as soon as you directly connect to any service it is impossible to hide your IP.

Because you always want to be careful what commands you are running as root. And GUI's don't let you see exactly what your doing. And one wrong slip of the mouse or simple mistake can cause major damage to your system.
And you last Q you can route traffic with iptables so in a sense you can setup a firewall as your router.
