If you've not done it already, don't convert your money at the US airport.
Use the ATM in China, or use a money changer in the airport over there. I don't know if it's an honest trade in China, so calculate the conversion yourself and count the money at the window.
In Taiwan and Japan, it's always been fair for me. In Bali and Thailand, the money changers have never failed to make a "mistake" when they do the conversion.
Drink lots of water and try to sleep as much as possible on to plane to reduce jet-lag. It won't be so bad going there, but it might get you pretty hard when coming back to the States.
Working a full day before a 1am departure isn't so bad.
If you're flying out of LAX, bring suit cases that can be opened or they'll force you to stand in the bomb detection machine line. Leaving on a Tuesday isn't too bad, but expect to be in the baggage check line for over an hour.
Have fun.
