You most definitely do NOT need everything in this guide i know i missed most of the guitars and a few other things. i also DID take the ammo from "fallen comrade" near the end. it is none the less a very good guide and if anyone follows MOST of the guide they should get the achievement no problem.
on a side note if you have a CHOICE after killing the dark one in the maze then you can get Enlightened and hostile by reloading checkpoint
