travel time from Shanghai to Hangzhou airport

Another question -

My friend and I are looking for the best way to travel from Shanghai to Hangzhou and approximate time it takes to get to the airport in Hangzhou?  Does the train station go to the airport?  Taxi?

Also, as far as train tickets are concerned - can you buy round trip tickets that you would use on different days or do you just buy them one at a time?
