Update quickfix list, recall vimgrep expression

I am using Vim 7.3 on Windows 7 Enterprise 32-bit.

I'm use the quickfix list a lot with vimgrep. I swap between lists by
the :cold and :cnew commands. However, after much editing, the lists
get out-of-date. When I cruise between lists, I often forget the
vimgrep expression, and the command history q: doesn't help after much
editing and flipping between lists. Is there a way to: (1) recall the
vimgrep expression associated with the currently viewed quickfix list,
and (2) refresh the list by effectively redoing the vimgrep? For #2,
I can see advantages and disadvantages to putting the repeated vimgrep
onto the command history as a new entry.
