War of the Ancient imo gives a more overall picture of the Legions army, how it fights etc, while the Rise of the Horde certainly gives alot more to understand how the legion works, thinks etc. Both books are important though imo. And as mentioned before Shadows and Light and Manual of Monsters are also very good for info on individual characters and what powerlevel they operate on.
A side question, Is the current lich king as powerful as the previous one? I mean Ner'Zhul was transformed into his state by Kil'Jaeden so what exactly happened to the current lich king in terms of a power boost if any?
