Hi Mike,
you can do this using SLD WMS.
The only thing you need to is set up a Styled Layer Descriptor XML, and
include in your GetMap url for instance using SLD_BODY (inline) or SLD
(access using a url). In the XML you also need to define how you want
your selection to be symbolized.
Best regards,
Bart

Is there any easy way to just query against a tabular attribute, rather than an XY? Must I use WFS queries to accomplish this?

What I'd like to be able to do is only display map features that have a table attribute equal to a particular ID. So in other words, I'd like to query the GIS data for features (individual shapes in a "feature class" vector data table in Oracle) that are equal to this ID, and display them on a map as WMS. I know how to do this through ESRI software, but I'm not sure how I could do this via OL and WMS.
