Same here, although I think I will get caught up on HunterXHunter next.
Yobo - I'd recommend Soul Eater first, it's funny and gets serious later on. I think Elfen Lied might be a bit heavy (and bloody, for that matter) for a first anime, and I say that because Hellsing was the first one I watched and the butchery literally made me sick at several points.
