I complete 6 dailies on the isle every day in about 20 mins. Can't really beat that.

What I did to get my epic mounts was run a bunch of heroics. It took me around a month to get the gold together for all my mounts. A good chunk of this came from selling enchanting mats. Which the market right now is kind of falling out.

I think the biggest gear upgrade you will get from starting out fresh at level 70 is a s2 weapon. This weekend is AV weekend you could get the honor for this piece pretty easily.

Go buy the "starter" seer's pvp set. While it may lower your spell damage you will be able to take a couple more hits from heroic npcs.
