Mount questions!

Ok, I've got two questions. I think one of them has already been
answered in my search.....but I didn't like the answer, so I'm asking
it again.

First question: Does anyone know of any way to raise Darkspear
reputation to exalted outside of the runecloth RRQ? So far, it seems
that runecloth is the only way (why can't I turn in boatloads of silk
><), because there are so few Darkspear aligned quests.

Second question: Orion Ryder mentioned buying his Black Stallion (in
Menethil Harbor). Does anyone know if any other factions besides
humans have a "hidden" mount like this?

For some reason, I've come to the point where I can't stand the Undead
bone-horse, and was hoping to manage a raptor by the time I was 45 or
so.
