This was ridiculously easy to make. Not sure it is exactly how you want it, but it is how you described it. I'm used to triggers, so I went with that. It's a lot easier.
First, you place a marine for player 1 and some burrowed zergling for player 2.
Then, create a camera.
Zoom out with your mouse wheel, and create another camera.
Go to player properties. Make player 2 a computer.
Go to dependencies and load the liberty campaign. I'm not sure this is necessary, though it only takes a second.
Make the following triggers:
The map is attached below. I used the HOTS editor, but it should open in WOL too, I think.
No, not necessarily. That's if you want units and stuff not found in multiplayer. Considering you're only using a marine and zergling, you can skip it. Though for anything else, it might be a benefit, yes.
The easiest way to zoom out is just to create a first camera, then zoom out with your mouse scroll and create a second one. In the triggers, apply the first camera with 0 seconds, then apply the second camera with x seconds (x being the duration of your zoom).
Just place some burrowed zerglings around the marine, set them to allied with the player of the marine, then set them to enemies when you want them to attack him (make sure to start campaign AI for the Zerg, or they'll stay burrowed).
