Traveling vide train from Shanghai-Suzhou-Hangzhou-Shanghai

Hi, I'm reaching Shanghai on 16/12/2013. Planning to buy 3 types of tickets for Shanghai-Suzhou, Suzhou-Hangzhou and Hangzhou-Shanghai. Can I collect all the tickets when I arrive at Shanghai Pudong Airport?
My flight is scheduled to arrive during midnite 12.30am on 16/12/2013, is there anyone to assist for collection of tickets?
