all of the parts will come with driver discs already (if not buying used), so there is no problem there.
You will need internet to activate win8, or to set up a user account with a Microsoft account (which is suggested), so you might want to take it next door once you get the OS up and running to get that out of the way (otherwise MS will bother you all day long about possibly using stolen software and such. super annoying).
Once you get the internet turned on at your new home you will want to do updates, and get the latest drivers for your hardware.
Congrats on the new place and the new PC
