Good book for getting started with Linux, I used it myself.

That wouldn't do what you want. Only root has permission to reboot/halt
the machine (for obvious reasons). I suppose that if you really wanted
to do that you could make halt setuid root and make it only executable
by owner and group, but I really wouldn't recommend that (I avoid making
anything setuid for security reasons). If you use GDM or KDM for your X
logins, those can be configured to allow reboot/shutdown from the
console without a root login.
