+ = toe in
- = toe out
Alignment looks good assuming it wasn't super expensive, better then I'd expect from like a $60-$80 chain store, but if you got charged over say $120-$150 you might be getting ripped off.
That is assuming there aren't parts limitations and instructions that conflict - if you told them maximum camber up front and they did max it out - that's on you, less then a tenth of a degree difference in camber - you're fine. Depending on parts you have in the rear there may not be much to adjust to improve it, but again less then 0.1 degree is negligible in my experience.
