Transport from HK airport to Lou Ho area?

Hi,
I will be arriving on Sept 5 to hongkong airport and going to attend a convention in Shenzhen, I read that there is a ferry going to SZ, the port is Shenkou terminal, Is this near Futian or Lou Ho district.

If I go to SZ by bus, can you help me how to get the bus going to SZ?

What is the best way to go to SZ from HK airport?

Thank you
