Vision Increase and Detection Abilities

[ThingInTheCoat]

I'm having some trouble here. I'm wondering if there is way to increase the vision range of certain units as well as to give detection to a unit that is not normally a detector, such as a Dark Templar. I saw the latter done to some hero units in the Resurgence custom campaign, so I know it's possible; I just haven't the foggiest on how to do it.

Oh yeah, and how do I alter a player's starting resource cache? I'm quite a newb with StarDraft.

EDIT: Since posting, I've figured all of this stuff out, so just ignore this thread.
