Okay, that's pretty normal for a Canada/USA light switch box. You'll have black/white, both of which are HOT when the switch is "on", and maybe a bare copper wire for earth ground.

Perhaps the Insteon modules are happy with the bare copper? It'll work, but is it safe? Gotta read the Insteon docs to know for sure.

As for running new cable to a switch box.. it depends upon where the outlet (controlled by the switch) is located, and on whether or not there's an unfinished floor above (attic), or ceiling below (basement). If not, then there'll be some (minimal) drywall patching needed after the upgrade.
