Train journeys

HI, I want to travel from beijing to hang zhou by rail. which stations do i need to use at each end of my journey. After a short stay in hang zhou I want to travel by same method to shanghai... . Can I purchase these tickets on this site and pay with uk visa debit card???. Can these tickets be forwarded to my hotel in beijing for collection on my arrival.

2. After Shanghai I need to take the bus to Nantong. Is it possible to buy bus tickets in advance as i know the period I want to travel will be close to national day holidays. I have used the Nantong bus service on previous visits and i think the service runs from the main Shanghai railway station terminal. Thanks in advance
