Besides all the good tips you already have:
You might have a "onchange" handler on the first WOPopUpButton doing a
"javascript:form.submit()", then updating the second listbox in the RR-loop
depending on the selected value of the first WOPopUpButton.
This is low-tech, not high-tech like AJAX etc. :-) and absolutely easy...
