For Burning Steppes, if you’re looking for a quest chain find Tinkee Steamboil and go on that fool’s errand of studying dragons of all things. You’ll get some red war gold ok experience, but it requires some travel, not just killing mobs so be warned.

The reason I mention it here is that eventually, it will give you an in with Argent Dawn and yet more quests which will grant you faction with them.

And, as if you hit level 60 before you have enough faction you won’t gain any through killing mobs, just by doing quests, this can be vital.

Oddly enough, if you have some level 60 friends who are willing to go with you, Alterac Valley Battleground can be a good place to grind. You can power level using the technique of tagging monsters in the area and letting your friends finish them off if they’re too much for you.

This will get you not only great experience, but nice amounts of cash, honor kills, items and faction rating with your side, so if you can convince some friends, it may be worth trying at even a low to mid 50.
