the best method for this type of product would be to have it crated, although this would also be the most expensive. i have used www.shipalliance.com for crating larger items for shipping. They did a great job with both have reasonable prices.
I would contact the UPS store. Usually if they pack it for you, they have some guarantees to go with it. If you insure this set of china and something goes wrong, you can get your money back, but that of course may not be as important as the china itself.
