If your really intent on recreating EQlive, a notion I just don't understand, then Allakhazams would be useful. The info for members is pretty extensive. I don't know that it's still the most accurate, I haven't played in a couple years.
On the other hand, you could just create your own content from scratch. It's not as difficult as you might think. And you avoid the massive headaches of trying to get all the disparate pieces of information, from numerous sources, integrated and into the database.
