Wise High Elf Generals try to include at least one Wizard in all their battle forces. I woud say that the high elf army is probably the most well rounded army. They have good ground troops and great flyers. Calvary is weaker than most but that is where the bolt throwers come in. Every army usually has one or two of these bad boys.
Chariots are also another good addtion to the high elf army.
I would suggest on getting the book even though the stats are here. You get things in the that I don't have time to include such as history and well history. Play smart and the High Elves will kick some ass for you. Anyway, when if come to the high elves you have to vary your strategy depending on which army you are facing. Skaven on the other hand is a different matter all together.
