My personal preference, if you want to get more "in" to universe than by just reading wiki articles, I suggest you go and take some Black Library publications and read them. If you've played Dawn of War, weeell... we all love it of course, but it is possibly not all faithful to greater lore presented in Codices and Rulebooks.

Books which I find quite entertaining, and enlightening, are all Imperial Armour books, the Eisenhorn and Ravenor, First and Only (and the rest of the "Gaunt's Ghosts" -series too), Imperial Infantryman's Uplifting Primer is a must-read and so is the Xenology.
