comparing gearFollow

I've tried to do my homework on this. I've read the Roguecraft 101 posts on EJ. I understand that you can convert the value of agi, haste, ap etc to a numerical equivalent and that lets you come up with a number so that you can decide which gear is worth more. What I can't seem to find is someplace that will tell me what values to use. They are only in the 101 post for BC level gear. So, is there a source for WOTLK level gear? Would using the t6 values be close enough? How much difference does spec make? I know the 101 post shows that it matters but...has that been worked out for the new specs?

I have the spreadsheets but of course the lower stuff isn't on there and neither is my old gear. Yes, I could put it in but it seems easier to just run the numbers when I have something worth doing it on.

Thanks for pointing me in the right direction.
