How to get to Tianjin Railway Station from the port and from Beijing South Railway Station to Novatel in Beijing?

We are travelling on the Princess Diamond, arriving in port in May. We wish to catch the bullet train to the Novatel in Beijing. Can you please advise me of the distance of travel and best way of getting from the port to the bullet railway station, then distance and best mode of travel from the destination railway station to the Novatel and all costs involved. Much appreciated
