Yes.  In fact, that is what my PIC development environment does
automatically.  You specify all the pins you use with /INBIT and /OUTBIT
preprocessor directives, and the remaining pins are automatically set to
outputs and driven low in the standard PORT module.

I'm not sure what you are asking about "regular resetting", but note that
high impedence is the power state of all pins that can be high impedence.

Just don't ever tied unused Vdd pins to ground ;-)
