So I think I may have passed from casual to addict

So I started a project recently that I believe pushes me out of the realm of casual WoW addict into the real thing.  I've made a spreadsheet of all my gear and then labeled it based on its strengths.  Then I've used that to put together different tanking sets (assuming best enchants and blue gems).  I'm sure I did something wrong, but check it out:

My Spreadsheet

You might note that my gear isn't really the best, but that's ok.  Some of it is pretty nice actually :)
