If you use Ajax.Updater, then the result would need to be in (X)HTML like you
said.

You could instead use Ajax.Request which would receive an XML doc which would
contain the values you need. Then you can do something like this:
$('id_of_city_field').value = city;
$('id_of_state_dropdown').value = state;
