Thank you all for the helpful, albeit exasperated responses!
I managed to get the texture pack into the folder, and it does read in the game now, however for some reason I can't select it...
Anyway, the point is that I'm closer, so I'll fiddle around with it and hopefully I'll finally be saved from the horrors of vanilla.
Anyway, thanks again!
EDIT: BADABOOM! Got it working, thanks again everyone!
