Don't Leave Me Hot and Hanging

How do I wire my new bathroom exhaust fan? The old fan has three functions (fan, light, nightlight) and therefore connects to a triple switch on the wall. It also means that there are two runs of wire to it. The new fan has only two functions (fan, light) and therefore only needs one run of wire. How do I wire this thing up; what do I do with the extra run of wire?

Just some more detail: One of the black wires was connected to the black of the fan connection. The other black wire was connected to the night and nightlight portions. All the white wires were connected together.
My assumption is that the run of wire that went to the fan will only respond to one of the three switch on the wall and the other run of wire will respond to two switches on the wall. So, do I simply:
1) Use the run of wire that was previously connected to the light/nightlight of the old unit to connect everything of the new unit; and
2) Not use the other run of wire at all, and thus "cap it off" by putting wire nuts on the end of it and leave it in the attic? This wire will still be hot as hell once I turn the power back on, so can I actually put nuts on the end of it and leave it in the attic?
Or does it get more complicated than that? Do I need to install a double switch in place of the triple switch and remove a run of wire entirely? I am hoping this last paragraph would be optional and wouldn't be required.
