Like you said, get rid of a trinket, try to replace fetish with dfo or reign, spyglass is a good trinket
try and get 1 sancti token for 4th sancti tier.
Try to replace crit/hit items with haste/hit items
Replace haste gems with sp or sp/haste gems.
Try to get a new cloak, spirit isnt usefull. Totc25 gives a decent cloak with hit. gives you chance to loose crit/hit items and you can use a haste/cit item
The only real diff I can see between you and me is a few hundred spellpower and a bit haste.

My armory, Im prolly in resto gear offspec but Ill log out as ele tonight.
on note: I pull around 10-12k dps in icc with 15% buff
If you did all this and dps is still below, its probably a rotation problem or you have lot of movement tactics for the encounters.
I just saw, glyph of flameshock isnt really usefull single target (boss) as far as I know, glyph of flametongue weapon or lava burst glyph is more usefull.
2 points from convection to fire nova might help in somefights aswell. I doubt you have mana problems.
always remember, SP is first stat for us and haste a close second.
