Printer Setup Utility does not exist in Leopard. If you want to reset the printing system, go to System Preferences>Print&Fax and control-click in the Printers list at the left of the window. At least, that's what I assume you are asking. If not, post back and I'll try to answer you.

I have used EasyFind and FindAnyFile but, for the most part, Spotlight works OK for me.
