That looks like a frostfire bolt spec there so I'm going to recommend the following changes to your glyphs and rotation:
Glyph of Improved Scorch, Glyph of Molten Armor, Glyph of Frostfire
For rotation my usual approach is...
vs mobs with less than 90k health: Frostfire spam -> instant pyro when it comes up -> More frostfire spam
vs mobs with greater than 90k health: Scorch x2 -> Frostfire spam -> instant pyro -> More spam
This is for trash, not bosses. The reason I don't bother with scorching things with less than 90k health is because they're usually dead before the improved spell crit matters so I've just wasted my time where I could have been shooting things instead.
Also I don't use living bomb as part of my normal rotation, the global cooldown used for that could be used for more frostfire bolts which will ultimately give you more damage output than living bomb will... There are exceptions of course where you want to be using LB as well, but for normal "tank and spank" single target dps, LB is a waste of a GCD.
For your gear, the first thing I recommend is getting a whole lot closer to the hit cap than you are now. All the +spelldamage and +crit in the world won't matter if you can't hit anything.
My guild requires that dps classes be able to put out sustained dps of at least 1500, other guilds probably have higher requirements, looking at your current stats my guess is that you're not there yet. You should be fine for heroics though and I recommend doing those... a lot. Get revered with Kirin Tor and exalted with Sons of Hodir for your head and shoulder enchants (Kirin Tor also gives you a nice dagger)
I'm by no means the final authority on anything, so other people's opinions may vary.. I'll link my armory here too though for comparison:
