shanghai, suzhou and hangzhou

Hello,
I will reach Shanghai Pudong international airport around 3pm in late Oct 2012.
Should I go straight to Hangzhou (for Xihu, Tomb & Temple of Yue Fei), then Suzhou (Tongli, Tiger's Hill) and Shanghai, or Suzhou, then Hangzhou and Shanghai?
From Pudong international airport, where do the coaches stop at Hangzhou and Suzhou?
Thank you.
