I have linked to shadowpanter's site before, but was there again today, and ran across this gem. I am almost 65 now, so it doesn't help me much until the expansion is out, but may help others -

So you know what pieces to keep an eye out for, have crafted, buy up in AH when you see them, etc.

The whole site is wonderful, really - but this page was a big eye opener!
