Jaden asked me to post about this so I am. I've found a few repeatable quests you can use to increase your rep with various factions: the first one is in the Shimmering Flats north of Gadgetzan in Thousand Needles. A goblin there will take loads of Lesser Bloodstone Ore for 6g a pop. The catch? people sell it on the AH for 1g/ load, and if you want to get it on your own, you have to mine it from Drywhisker Gorge in Arathi. Rep boost goes to the Steamwheedle Cartel, not sure which branch. Probably gadgetzan. The second one, which you might find more practical, is in Gadgetzan. A gnome there in the north side of town gives a repeatable to find hippogryph eggs in Feralas. the eggs themselves are lying on the ground in Feralas in the south/southwest corner of the High Wilderness, and you can only carry one at a time. Once you get one, bring it back to Gadgetzan and stick it in the egg-analyzing machine. Depending on the quality of the egg you find, you get a care package with items in it and a rep boost. here's a map: http://i41.thottbot.com/Interface/WorldMap/Feralas/Feralasbig.jpg as I said, south/southwest corner of the High Wilderness. I think the rep boost for this one goes to Darnassus. I also have a repeatable that boosts my rep with Gadgetzan: bringing Wastewander Water Pouches 5 at a time to a goblin in the east corner of Gadgetzan yields a care package with potions and food, and a rep boost with the goblins. The pouches come from the Wastewander bandits you see in northeastern and eastern Tanaris. A fourth repeatable is in the Hinterlands; a dwarf there will take Troll Tribal necklaces 5 at a time for a rep boost with the Wildhammer clan. Trolls can be found all over the Hinterlands pretty much anywhere you choose.
