Shanghai Info

I will fly to Hangzhou in June 2013, I have plan to visit SH and Suzhou. For convenience, which one I should go first ? Hangzhou - Suzhou - SH? or Hangzhou - SHi - Suzhou ?

After SH I will go to Anxi, near Xiamen, Fujian Province, Is there any long distance soft sleeper bus (night) ? How much does it cost ? which station do I can get this bus ? and how long will the bus take ?

Thank you very much for your help :)
