Is there some specific location along the neck where a cut must be made for it to be halal slaughter? Or can one cut anywhere along the neck?
According to the Department Of Halal Certification:
The windpipe (throat), food-tract (oesophagus) and the two jugular veins must be cut.
Slaughtering must be made in the neck from the front (chest) to the back.
This is just a partial answer, I'll try to find evidence from the Hadith and Quran to suppprt this but if anyone finds it, feel free to edit this answer with the revelant quotations.
