say i do the wire install, can i cut the gray wire in this picture to make my d0 wire longer so it will reach that alternate d0 point?: /http://users.belgacom.net/bn257386/x-ecuter2/tutorials/lite-small-wire.jpg

can i do this for the headerpin install, but just cut the other gray wire instead?

i'm not too sure, but if you're trying to extend the wire, i think you can just solder another wire onto the d0 wire and then solder the other end of the wire into the d0.

yes it will work, just make sure to glue/tape up them wires
