So I am able to go another zoom level down which gives me a square centered map image of 256 px wide in the center of my 557 X 557 div with white space surrounding it to fill in the rest of the 557 px. This is something which i dont want to happen.

Looks like you have not set your resolutions array in OpenLayers
correctly. Do a GetMap request on GeoWebCache and set the resolutions
option on your OpenLayers layer to the same values as the one you see
in GeoWebCache's GetFeatureInfo response.

This is something that you should report with more details about when
it happens in the GeoWebCache trac or on the GeoWebCache users list.

Regards,
Andreas.
