If your other layers come from the same wms, you can combine them into
one OpenLayers.Layer.WMS instance, and have alpha opacity on the
resulting image.
Assuming you have layer called base and overlay (the latter has opaque
shapes), and you have
map.addLayers([
new OpenLayers.Layer.WMS("base", "/geoserver/wms", {layers: "base"});
new OpenLayers.Layer.WMS("base", "/geoserver/wms", {layers:
"overlay"}, {isBaseLayer: false});
]);
you could change that to
map.addLayers([
new OpenLayers.Layer.WMS("base", "/geoserver/wms", {layers: ["base",
"overlay"]});
]);

Andreas.
