Your questions are rather too specific to be of much use without the code
itself.
How are you making the call back to Wicket? Are you writing your own
AjaxBehavior?
If so, AbstractDefaultAjaxBehavior, which most of the Wicket AJAX
functionality extends, uses getCallbackScript(boolean) to generate the
wicketAjaxGet(...) bit of javascript. That function internally calls
getCallbackUrl(boolean). You can override this function in your behavior and
add some GET params on the end (return super.getCallbackUrl(...) +
"&foo=bar"). You can then retrieve these from your respond method with
RequestCycle.get().getRequest().getParameter("foo").
For some example code, see the list editor at http://londonwicket.org
