What I have found works best is to split the functionality between WMS 
and WFS. For display of your data, add it has a WMS layer with 
appropriate SLD. You might like to look at SLDSelect (and the OL example 
for it) to show how much you can do with WMS on display side. For 
querying, use WFS. You get the high speed drawing of 100,000s of points 
with WMS and all the power of WFS for querying.
