As far as the glyph of indominability goes, even though you don't see it in your HPs, the armor is more EHP than any trinket you probably have at the moment. Satrina's and Skeleton Key are the only two that out do it atm (not counting UO obviously).
As far as specs and breakdowns go, take a look in my guide, however come 3.3.3 you'll probably put revenge back in your rotation, but for now you don't need to spec it. The 15/3/53 spec I have in my guide is a really balanced build that provides pretty much everything you need unless you want 5/5 demo shout and 5/5 commanding presence, in which case the 5/15/51 build in my guide probably would be a good way to go for you.
