Make sure your wmsBaseLayer has the same projection as your Bing base layer (EPSG:900913). Have a look at the http://docs.openlayers.org/library/layers.html layers documentation and note particularly this part: "The currently active base layer determines the available projection (coordinate system) and zoom levels available on the map".
