i'd say thats a good way to do things.

presumably root is immune from most things "ian" might try to do due
to some evil jpeg image or email virus (hey, buffer overflows happen -
even to mutt and pine)

running "su" in an xterm is probably fine too. if you're paranoid you
should consider enabling the "Secure Keyboard" option in the
Ctrl-MouseButton1 menu from your xterm whenever you type in
passwords. that will stop (or at least make it very difficult) for
other X programs to grab keystrokes from that xterm.
