as far as gear goes, you're really looking good. I'd swap your chest enchant to a 275 hp one, and cloak enchant to the 225 armor one (you can afford to lose the +def). Your spec looks fine (you've got the essential points correct, and while everyone has an opinion about how many points in imp. disciplines vs. imp. revenge or focused rage, those don't matter a whole lot) The only spec change I would advise would be dropping all points from imp revenge and not using it at all, or putting 2/2 points in it. It doesn't seem wise to me to go halfway.
