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.
