what is the best route for the trip of Wudangshan, Wuhan, Zhangjiajie and Guilin?

Hi,
We are planning a trip in 2011. We intend to tour Yangtzi river and visit Wudangshan, Wuhan, Zhangjiajie, and Guiling. We have couple of questions.

What would be the best route for our intended trip?
What is the best way to get to Wudangshan? To your knowledge, how many days shall we stay there? Any recommendations on hotels?
From Wudangshan, what is the best way to Zhangjiajie?
If we order train tickets through your web site, are you going to deliver the tickets to our hotel rooms?
Besides the cruises, are there any other options to experience the Yangtzi River individually?

Thanks for your help.
Mary
