You need to find out what the projection of your shapefile is and set that in the declared projection/SRS box. Once you have done this you then need to calculate what your required map bounds are in EPSG:900913 (the Google Maps Projection) - of the ones above 1562483.09425,2004362.9156249,1563547.292875,2005427.1142499 looks most plausible (big numbers are what you are looking for as Google measures in meters from the equator/Greenwich meridian) to use in your WMS request.
