Voltage follower realized by using AD8000 question

Hello Guys,

We plan to implement a  voltage follower by using AD8000. The schematic design likes below

My questions are:

1. Is this implemented? Do I need to add feed back resistor between feedback pin and input port?

2. Can i need to connect output pin and feed back pin external?

3. Pin-9 is let floating, is this ok?
