Money is often a large problem of mine aswell. I can't balance the speed at which I'm leveling with my income at all. It's nearly impossible. The best way I've figured is to grind to keep my gathering professions up, and sell the materials I farm on the AH.

I've also adapted my quests around killing beasts/humanoids only. Beasts for the skinning, humanoids for the sheer coin and cloth drops. Also, make sure you have an alt "AH" toon to sell all your 'junk.' This helps a lot in bringing a lot of extra gold. Just mail all your cloth/leather/greens/blues/purps to the AH alt and every night before you get off or every morning when you get on put it all up on the AH. Before long you'll have plenty of money to keep yourself running.

And congrats on 60!
