In New Moon, we are introduced to the Volturi (which, Caius is one of the leaders of). We are also more introduced to the Quileute pack, and what the link is between the vampires and the werewolves.
Werewolves are the only thing strong enough to destroy a vampire, besides another vampire. Vampires are basically the only thing that can kill a werewolf because the venom is extremely poisonous to them and kills the wolf instead of transforming them into another vampire.
Caius realizes how powerful the Quileute pack is, and that is why he is "afraid" of the wolves.

no there is no illusion in the new twilight
Yes. New Moon is the next movie/book after Twilight
In the order Twilight, New Moon, Eclipse and Breaking Dawn
I personally think twilight is better but that's just me. I thought it was better because I had a picture in my mind already when she described things because I saw the movie already but that is just my opinion.
