The drings/tow would be $15 to ship and the case I will have to check on and get back to you. Im not sure I would trust putting the stuff in the case but will look at that too.
If you can find a Nikon 12-24 F4 it is a great wide angle dx lens. What do you want to shoot, overall scenic, macro, wildlife? I would master the camera and composition before you start worrying about filters, you will just get frustrated.
