While using this guide I found a badly formatted line (line 130 in Notepad++ not showing the arrow to the coordinates) and a misplaced coordinate (line 131 in Notepad++ coordinate would send the user to the far northwest corner of Borean Tundra, which makes no sense at all).
I'm planning on going through the full guide on my priest alt, so if I find any more bugs in it, I'll update this guide further.

Corrected guide is uploaded here: http://www.rpotor.com/wow-pro/002_70_72_Jame_Borean_Tundra.lua

Added to the current repository version. Thanks!
