Wow, if not for your bow-tie I'd have assumed the tux was black. Between your descriptions and the photo, I'd say that the 8810 Midnight Blue looks perfect !
I made my tux with WW Chan and I let Patrick make pretty much all the decisions for me and he will steer you in the right direction. They may not be able to give you the completed garment before you leave but can mail it to you. Also if you absolutely feel like you need to see the cloth before ordering, you can have them mail you some swatch samples. Best to discuss this with them over the phone.
I don't mind if the garment isn't completed before I leave so long as all necessary fittings and adjustments are completed in time, last thing I'd want to do is take a nice expensive Tuxedo and leave stuffed inside of a suitcase for months on end collecting dirt and dust over here. Regarding fabric choice I think I will defer to the expertise of Mr. Foo, and ask for Smith's 8810 (or something of equal quality and appearance if unavailable).
