I have the following code, how do I improve it by adding code to display to the user that the shipment method was updated to X shipping method? (there are 4 ship method choices in the radio button code; Standard, Second Day, Next Day, and Choose every time.)

You could modify the getDefaultShipmentMethods method, to return
selectItems whose value is shomething like a ShipmentMethod bean (Object), rather then a shipmentMethodCodeId. The ShipmentMethod bean can contain a property (via something like getName) name, that contains the name besides a property shipmentMethodCodeId. That way you'll have access to both.
Then you have to add a property customerSession.customer.defaultShipmentMethod of type ShipmentMethod to your customerSessoin.customer bean.
Something like (not checked for syntax errors btw):
