Barbara,
What a great way to celebrate
For your photography dilemma, you must decide if this is
1/ a trip to China during which you will be taking some photos, or
2/ whether it is a photography trip which happens to be to China
I am mostly in favour of tripods but not for travelling in China.
Try a small beanbag for $10. Fits into your backpack, almost no weight
and the camera just sits happily shooting on the timer, if you need that
stability. For most shots though, you can brace the camera against
something.
The 18-200VR is a wonderfully compact zoom but is not a low-light
lens at f/3.5. Realise that cash may be a consideration but you should
really consider a
faster low light prime. The 50mm f/1.8 is a real
bargain at $100. Very light and compact and will get you images which
would be impossible with the 18-200VR. In certain circumstances, you
may not be able to use flash and a low-light lens will rescue you for
available light shots.
While it is a great lens, I would leave the 60mm at home, as well as
your kit lens ( already decided ?

and just take the 18-200VR, plus
a low light lens, the 50/8 or 35mm f/2 below . . .
More expensive but possibly more useable at about $250.
Very lightweight and compact, with a slightly wider
range than the 50mm, so more useable for general walking about.
Re your storage : on trips like this, the worst thing is to run out of
storage. On shorter trips, I travel with about 6 or 7 Gbs of CF cards,
or a laptop on longer trips. Let's say you shot 100 images every day
on a 2-week trip. That is 1400 images. a 1Gb CF card will hold about
220 D70 jpg images at the best quality. ( 100 daily shots is conservative
on a trip like this, it will lilkely be more
You can reduce the quality setting to increase storage space on your
CFs but most people use the highest quality, in case their shots are
perfect for printing.
Check out the media and storage forum to drive yourself crazy on
storage methods, but you will need something. The least expensive
devices are about $150. Great capacity but subject to occasional failure.
There's no perfect travelling storage solution :-(
Take a supply of zip lock bags, several sizes.
Also, a small folding umbrella so you can still use your camera in the rain.
Sounds like a great trip, prepare well
