I have a trigger using the event Unit Enters/Leaves Range of Unit, but it seems to want a specific unit. For the sake of brevity (and saving time for me), how do i set the trigger to find a unit that enters range of any of a specific type of unit?

Using your example, you could double click or Ctrl + click on a Stalker to select all of them and then Shift + click the left-most Stalker listed on the HUD six times. This would remove six Stalkers from the originally selected ten. Whether this is any less cumbersome, you be the judge.
Instead of doing subtraction to know to click six times, find the fifth stalker, (number you want + 1) and repeatedly shift click that one until there is no fifth stalker.
To enable upgrades or set other special properties for a map you have to use a trigger that is executed at the start of the game.
In the map editor, Modules -> Triggers (F6) opens the trigger editor:
The only default trigger is "Melee Initialization", which is executed at the start of the game. New actions can be added to this trigger by choosing New -> New Action (Ctrl-R) in the right pane's context menu. Searching for "upgrade" brings up the correct action to add:
Double-clicking on Upgrade: (No Value) then shows a window that lets you choose which upgrade you want to enable for the player.
The action created this way will be executed at the start of the game and enable the selected upgrade.

Are you sure you want to use a trigger for this? It sounds like the functionality you're looking for would work much better as an aura-like ability.
I've been fiddling with my SC2MapEditor -- I don't think there's a simple way to implement the ability with that event, as it's designed to work with a single unit. You might could try something with unitgroups, but even that returns only one (rather than all) of the units in the unitgroup.
It might also help if you informed us what you were trying to do.
