On talents: you really should go for Vigilance. When tanking in raids, in my experience you don't need shield specialisation so much, I mainly use 2 points as a filler, and you could put the points somewhere else besides the 1 in vigilance (like in imp bloodrage or 2 in cruelty). (vigilance for threat and improved bloodrage for more rage on a clicky, cruelty for more crits.)
On glyphs, currently glyph on devestate is one of the strongest protwarrior glyphs around, get it love.
On gearing I woukld advise to at least get the saronite swordbreakers, they're a huge upgrade over you current bracers. Also you could get a stronger piece for your belt: either through frostbadges or even getting an indestructible plate girdle crafted. It's still a pretty strong piece because of 3 (with buckle) sockets.
How to spend you frostbadges, I'm not sure about that myself.
Try looking at the non-set pieces you can get for triumph badges, for instance: I value the triumph helmet higher then the tier piece, even if you need to give up the 4 set bonus for it. Also. the non-set triump items are1 tier above the non-trophy-t9.
