I wish to go to Nanjing from Shanghai. Can you advise on below schedule to do so please?

I am flying to Pudong airport arriving at 7.30am. I am thinking of going by Maglev after exiting the airport and then take a line 2 subway train to Hongqiao Station to take a bullet train to Nanjing. For a first time traveller to the two cities, is this the best and quickest way to do this and what tips are helpful to achieve this
