Please reply also to the OpenLayers list! If the WMS request works in your browser there should'nt be a problem with the geoserver setup. I suspect the problem in your OL configuration. Usually I define a maxetent and a resolutions/or scale array for the map and then do a setCenter() at the end of the config ...
Please show us a minimal example. Without that it is impossible for us to locate your problem.
