Ran Code: Changed Priviledges, Services, System Files, HD etc.

I just wanted to print my login screen in Single User Mode, used codes I didn't write down (from off the internet, no less) and I cannot remember

ls | lpr

and/or

#/bin/sh

gnome - terminal

echo -n "new terminal"

please someone help me, i did something very stupid!!!

CRDs-MacBook-Pro-15:~ cat$ ls -a

. .bash_profile Music

.. Desktop Pictures

.CFUserTextEncoding Documents Public

.DS_Store Downloads Send Registration

.Trash Library Sites

.bash_history Movies ytb.uid

I ran a code I got off the internet and I am paying for it dearly. All application Services are no longer active. I am missing entire folders and pref. panes. I erased my partition, reinstalled 10.6 and it changed nothing. I cannot remember exactly what it was, however, it could be. Console says so many scary things:
