The rules you need for the newcomers above and a bounty of ogor lore can be found in Battletome: Ogor Mawtribes, which is packed with warscrolls, battle traits, spell lores, and tons of awesome artwork.

You can get this essential accompaniment to an ogor army in both its regular hardback edition and the Gamer’s Edition release, which includes a portable, softback version of the battletome alongside a full set of warscroll cards for the faction.
