Things are finally working fairly well for the customers grid (although I've not yet taken any speed issues into account). I removed the index.ctp file, since it was largely useless and I figured out how to render directly to the element. I also moved most of the jqGrid XML code into the application controller, since it will be reused by most of our controllers.
