DK Tanking help, please?

[Zummy]

So I finally got back to warcraft. I haven't played since 3.1, but I heard DK's are still good tanks. Anyway, I just managed to get def capped (548), but I only have 21k hp.

The World of Warcraft Armory (http://www.wowarmory.com/character-sheet.xml?r=Lightning%27s+Blade&n=Segue)

Don't mind the specs, I'm currently changing those, but what advice do you have for gearing my character for tanking?

Run lots of heroics, do the daily heroic, and buy all the badge gear. There's some good quality stuff.

3.3 will be landing soon meaning all heroics will drop Triumph badges, you can kit yourself out with a full set of T9 in about a week of solid farming.
