What other powers they might have? Well, it depends on what sort of fantasy you're aiming at. If you go with traditional legends, they're not a playable race, what with being rage-filled killing-machine predators. Sure, it makes for great roleplaying [angst, angst, ANGST!!], but if you're worried about what 'additional' powers they have, I'm willing to bet it's not an RP-heavy game. If you're looking at the basic D&D lycanthrope, then the stuff you've listed is pretty much it. If you want more of a World of Darkness feel, I'd suggest looking into some of those books; the game is designed around supernatural characters, after all.
No offense meant, though, but I really don't see what the big deal is about werewolves or vampires or even a mortal that decided lichdom would suit their purpose. I pretty much play humans in most games and let my playstyle, not my special abilities, make the difference. To each his own, though.
