You should be able to add additional parameters using the extraParams config on your proxy.

By default, grids read using GET.

You can probably set to POST using something like the following:

Ext.apply(Ext.data.proxy.Ajax.prototype, {
	actionMethods : {create: "POST", read: "POST", update: "POST", destroy: "POST"}
});
