I would ditch the glyph of revenge, while a great glyph for leveling you really aren't going to have to worry about rage once you hit ICC, or rather once ICC hits you. for ICC tanking i would take GoVigilance, or GoDevastate for threat. Swapping in GoTaunt where necassary fights.
on a more personal note. i wouldn't take Imp.Disciplines+GoShield wall in ICC, theres only a few periods of huge burst damage in ICC like there was in ulduar or TOC, except LK and festergut, and his encounter favours the unglyphed CD since you're only going to be eating the 3rd inhale once.
