Okay, wow, I almost feel like apologising again, though you know that my being late to reply is not *entirely* my fault. Anyway, I'm not entirely sure if you're still pursuing this idea of the Dire Wars or not. But I can still send you a note about lycanthropy and Lycaon.
I kinda hope you are still doing this, because that is a cool idea, though different from my first impression. xD At any rate, I think you have a point about wolves tending to be more positively portrayed. Though of the three wolf characters that are coming to mind two are villains, but that's just my experience.
Well Tolkien wrote a bunch of stuff, and pretty much every work has a different style. "Smith of Wootton Major" is dreamy, "Farmer Giles of Ham" is a comedic parody (of chivalry fantasy),
The Silmarillion can only be described as Biblical not only for its matter and magisterial tone but because it's a compendium of various works. I think a good place to start would be
The Hobbit, since it sets the stage for
The Lord of the Rings in more ways than one.
