So the right-rear really is still toed out? That's not so good.
Ideal toe angle depends on a lot of things. For the street, you want "a little toe in" all the way around. It helps keep the car nice and stable. A little toe out in the front can help the initial turn-in, but at the cost of making the car feel quite "twitchy". Good for an autoXer, not so good for a daily driver. Or even for a track car, for that matter!
I'd be a little worried about the difference in caster in the front. It's not a big deal, but it's better for it to be even. And it shouldn't have been difficult to change.
Not sure what the "thrust angle" is measuring, but I would assume any issues there would go away when you got toe-in on both rear wheels.
