I've been using "sudo !!" (which I pronounce as sudo bangbang in my head) for a while now, mostly with vim for editing stuff in /etc. It's very nifty.
Another nifty tool is vi editing mode. You run "set -o vi", and now your shell takes vi modal editing commands. That along with Ctrl-r for reverse history search has made life in the shell so much easier. Bash has a ton of little stuff like that built in. Zsh has a few more.
