I'm travelling from Shanghai Pudong Airport to Suzhou.

I know the bus is easier but it starts only at 9am while my flight arrives early at 6am. I'm thinking it will save me time if I take the maglev to Longyang, transfer to metro to Shanghai Station and take a high speed train. Am I right that if I take the first maglev at 7am out of pudong I can reach longyang within 10 minutes, and it's a further 40 minutes to get to shanghai train station via metro? What time should I book the train to suzhou from shanghai Station? I plan to book via this site and noticed that there is a train scheduled to leave suzhou from shanghai Station at 9.17am. Is it OK to book that train?
