The tech was lazy. He probably didn't bother with the rear and moved right up to the front or he would have been able to get the thrust angle dead on. The thrust angle isn't all that bad and is probably not contributing much if any to the strange handling you're experiencing.
The two different readings on the front toe would have been because the steering wheel was slightly off center. That is it was off before and is now centered, or it was centered before and is slightly off now. Sometimes total toe means more than individual toe.
Please be aware that although you can't adjust caster and camber on our cars without adding the adjusters, those angles are still important. You really should try to evaluate the alignment settings by observing ALL of the angles, not just part of them. Caster and camber can effect handling too.
I believe you are correct on the negative and positive toe. Someone correct me if I'm wrong, but that's the way I rmemeber it.
It sounds like he hit the front toe where I like it, as close as possible to zero as bossible while still being slightly toed out.
