I don't know of one that does profiles, but you should get a copy of the Sysinternals suite
. That has all sorts of process and other tools from the legendary Mark Russanovich, and is generally considered indispensable.
It's worth having for it's Process Explorer (task manager's big brother on steroids with attitiude) alone:
"End It All" might be useful for Sunday afternoon if things don't go well though!
