Answer 1

you can use removeAttr

   $('#item_shipping_true').click(function()
{
  $('#item_shipping_cost').removeAttr("disabled");
});

$('#item_shipping_false').click(function()
{
  $('#item_shipping_cost').attr("disabled","disabled");
});

see demo in JsFiddle

$('input[name="item[shipping]"]').on('click', function() {
   if ($(this).val() === 'true') {
      $('#item_shipping_cost').removeProp("disabled");
   }
   else {
      $('#item_shipping_cost').prop("disabled", "disabled");
   }
});

You would like to use JavaScript like this:

   $('#item_shipping_false').change(function() {
      $('#item_shipping_cost').prop('disabled', false);
    });
    $('#item_shipping_true').change(function() {
      $('#item_shipping_cost').prop('disabled', true);
    });

​ This is complete example of your case.
