Set GPIOs to high impedance

Hopefully this is an easy question:

To set up a GPIO to high impedance mode, I have to configure it as input?
If I want something connected to ground at this pin, I can set it to an output with low level?

What I actually want to do, is enable and disable resistors, witch are conntected to the GPIOs. So that some are connected to ground and the others are floating.

Thanks for any help!
