Well no great mystery - instead of creating your location layer as a 
vector layer, you create it as a WMS layer. However, if you want to 
query/filter, you create a wfsProtocol object for the same layer on your 
server and use that to query it. Note also the SLD-select demo also 
which is good for displaying selected geometry that is too large (but 
note there are issues with geoserver which doesnt honour SRS).  You cant 
use the style trick in CQL-Filter example, instead you can put the 
returned WFS objects into a vector layer created for just this purpose. 
I've been explaining the detail and some sample code on the "need a 
little help with this ( user input & wfsprotocol.read )" thread recently 
on this list for this way of doing things.
