I wouldn't bother with all those abrasives. You should be able to get a good range of wet and dry grits from any good hardware store or car parts store. It might be worth getting the 2000 grit but the rest you should be able to pick up much cheaper and more of! I do!!!!
I would also perhaps leave out the aerosols - these cant be shipped by air as far as i know. You should be able to get those from a local model shop alot quicker than waiting for them to get shipped by boat. While your there you might as well pick up some Tamiya masking tape.
