Answer 1

use Ext.each to iterate an array :

var sm = prodgrid.getSelectionModel();
delbtn.on("click", function () {
    var sel = sm.getSelections();

    Ext.each(sel,function(data){

        /// your stuff
        Ext.Ajax.request({
           url: 'products/delete',
           //   method:'DELETE',
           params: {
               'prodid': data.id // the parameter
           }
        }); 
        ///// end       

    },this);
});
