Travel from Xu Hui District to Shanghai International Airport

We wish to travel by rail from Regal Shanghai East Asia Hotel at 800 Ling Ling Road Xu Hui District to Longyang Road Station then travel by Maglev to Shanghai International airport. We will have an airline for departure.
What is walking route, then various trains etc?
What is the cost and how do we purchase the necessary tickets and where?
Many thanks
