WoW - Ogri'la Faction Tips @ Official Site
The official World of Warcraft site has been updated with a selection of Ogri'la faction tips.
Your first goal is to reach neutral reputation with Ogri'la, as you must be neutral to interact with the Ogri'la questgivers and vendors. To start the process, talk to the ogre Grok in the southeast corner of Shattrath's Lower City - he should be hard to miss. He sends you off to see Mog'dorg the Wizened in Blade's Edge, who will begin the quest line that will bring you to neutral with Ogri'la upon its completion.
