User blog:Aresius King/Introduction to the Warhammer World should get you onto the basics of each of the factions - start exploring from there and look at the Sources of each page if you want to go deeper ^^

The easiest way to get a well-rounded view of each playable faction is to search for the armybooks, titled Warhammer Armies: [Faction]. If you want to go real deep, you can also look for the RPG books.

As for novels, Black Library has plenty of them and should have some sort of list of publications. My personal favourites are the Gotrek & Felix series, but there are many, many others ^^
