I liked the movie...although maybe it was a bit too fast. For those, with doubts...
Lucian and his gang of human turned lycans used to protect the vampires from the uncontrollable, ones, who once turned were permanently werewolves.
Yeah, apparently those born a vampire do age to a certain extent but those turned don't. Even lycans for that matter.
As for lycans & vampires dying by means other than sliver bullets and sunlight, I think apart from that what is meant is immortality with respect to natural causes. If someone were to severe a vampire or werewolf's head, how would one expect them to live after that? What they probably mean is if left alone to lead their lives they wouldn't die. This was there in part 1, 2 and 3. So, that's what my guess is.
