For what you paid, I'd make them ante up the money to fix the turn signals. That's the least they could do. The TS sets are about $15 a set, and the plate brackets are about $20. If they tell you otherwise, they can stuff it.
The front lights bolt onto 2 holes right behind the fairing. The tabs are part of the main fairing stay, so if the guy cut them, I would wonder what other hacking he did, and take my money back from the dealer, since you haven't actually taken delivery.
I'll grab some pics when my wife gets home, so I can use her DSLR.
Also, check the taillight, its probably integrated.
Here is what a very clean, well sorted Z goes for.
