Hi Connie,

Here are some suggestions:

From Pudong International Airport to Nanjing Road East: Take the Airport Bus Line 3, get off at the Longyang Road Stop, walk about 90 meters and then take the Subway Line 2 to Nanjing Road East Stop.
From Nanjing Road East to Cheung Huang Temple: It is very near, you can walk there for 20 minutes. For bus, you can take the 801, 64, 17 and 576.
To Hangzhou, first, walk to the Renmin Square Subway Stop and take the Subway Line 1 to the Shanghai South Railway Station. You can buy a train ticket to Hangzhou. There are many trains available, including bullet trains.
To the World Expo: first, walk to the Renmin Square Subway Stop and take the Subway Line 8, then get off at the Yaohua Road, then walk to the Shangnan Road Entrance.
