At 50 you can look at the cloak and at 60 the belt/shoulders/gloves. I got the belt first as it was the biggest upgrade for me stat wise.

Also, if you can get into a trash rep farming ICC10/25 group then the www.wowhead.com/?item=Ashen Band of Courage is good as well or you can 5-box ICC10 trash for the rep. There is a thread or two about it, Maxion also did a vid I think.
