My question is, could this be one of my contributing factors in the instability of the car? If I was toe'd out, maybe the car under load was trying to go the direction of the toe and it started to fight itself... just guessing.
For sure - bad toe settings will create weird handling characteristics and accelerated tire wear. Camber contributes to tire wear but not as much as toe in my experience.
The alignment report is a tell-all but based on what you said it definitely sounds like your toe is off in the rear. It shouldn't be a problem getting it back to spec since you have adjustable rear toe arms.
