Well, I did me some researches (and bribed me high-INT kid brother Gogmoth to helps with the mathifications) and here be the some total of what you needs to get to exalted with Faction Ratshag. It be a long, pain-in-the-arse rep grind, but I thinks we can all agree it be worth it.

To Friendly: 875 Gnomish Marriage Proposals
At Friendly, Alliance types learn basic orc communication, such as: "Axe", "Mommy", "Rep grinds is Da Poop!"
To Honored: 2358 troll hookahs
At Friendly, adventurers may purchase Rat Bicuits - restores 874 health over 27 seconds
To Revered: 1124 Murloc Cufflinks (gold, not silver! orcs is allergic to the silver)
At Revered, Alliance types learn advanced orc communication: "Wait fer the dang sunders, you stupid bugger!", "That S3 axe would go well with my weapon collection", "I am one tough hunkerglubber", "Rep grinds is Da Poop!"
To Exalted: 3846 pair Ogre Undies, 427 Naga Nighties, 1 Uther the Lightbringer's Garter Belt with Pink Roses.
At exalted, adventurers may purchase a really nifty tabard, bottles of Ratshag's Jungle Juice - makes you slightly tipsy and restores 4200 mana over 30 seconds
Alliance types may invtite Ratshag to run instances with thems afters they become exaltified.
Where does you go to find these items? Buggered if I knows - I can't be bothered to keep track of the details. But I does know that all faction reward items is purchasable from Ratshag Faction Quartermaster Boy Friday
