"show reload" comes in handy once you executed "reload in", it will show you the time left you have on the router and, of course, if you don't feel comfortable with that you could always cancel it by typing "reload cancel". "show ip flow top-talkers" is awesome, unfortunately not available in platforms like 7600's. Off the top of my head I find very useful a lot of CEF commands like "sh ip cef exact-route" or "sh ip cef prefix internal", they will show how exactly the forwarding of packets is being done.
