Not until you're 85, IMO. You'll still find quest rewards more useful through Outland, Northrend, and into all the Cataclysm stuff. I'd wait til at least 80. You'll have plenty of money to powerlevel it up to 450 and start getting the good stuff. Tailoring only item enhancements and all that jazz.
Hope you've at least saved all the cloth you've picked up since your 1-60. Buy a couple bank tabs and some 16-slot bags. Fill them with stacks of each cloth.
