Man, I respect ya, you have too much patience
I looked at the walkthough and it didn't
spell out how you got the cheat book so I felt like just saying it...
So does anyone know where I'm meant to go for Anya's quest when it prompts me to speak to neighbours?
first off, are you aware that this quest is unfinished? this is not the final update, the quest won't be complete until 5.0.0. I didn't go down the route you did, but if it is something you can do, why not just try talking to everyone in the village and if nothing happens, then clearly the quest is not finished. or heck, maybe the read the quest info and it will tell you whether or not the quest is finished.
