I believe that any input pin must be pulled either up or down depends on the use. If there is a switch normally most of the people, pull up a resistor at the input pin, and the switch goes to ground.

Now for the rest of the pins personally if the pins are output and digital, i leave them floating, but i use the command:

PORTx = low

Just read Ioannis previous post. It is really useful info. Thanks a lot.
