Suggestions for my gear/gem/enchant choices?

Hey fellow mages. I'm having a slightly difficult time figuring out why my DPS is extremely very low compared to other mages when I either look on meters or logs. If possible, I'd like some criticism, help, and/or ideas as to what you guys think of my current gear/gem/enchant choices, and if you have any suggestions.

After some tinkering, this is what I have as of "right now" of this posting:

So a bit of explanation as to why certain reforge choices were made, obviously in my old gear style I always made sure I was 17% (hit capped), yet when I check a lot of raiding mages, they are sitting just a little over 16%, but under 17%. I have read the EJ Forums that says Int being the most 'powerful' stat.

As for some reforge choices were to haste instead of crit, I am unsure about that because I have been told from a few other mages that after reaching a certain % or soft cap will yield more DPS and then followed by Crit in terms of how important the stat is, however isn't Fire supposed to be heavily Critical Rating dependant?

I have mats and am just waiting for enchanters to log on to enchant power torrent, +int to bracers, and the +20 chest stats.

What suggestions do you have that I can improve the gear/gem/enchant choices? I really dislike being low out of all caster DPS (even if I don't fail at boss mechanics).

EDIT:
It may also be my execution & rotation. For Combustion, I really don't know why the dot tick is so generally low (possibly being ignite munched by LB or something else?). I use Combustion usually when I have Critical Mass (or warlock debuff up on the boss), Living Bomb, a Pyroblast dot, and usually a 30-40k Crit from either the Pyro or Fireball. Is this using Combustion effectively or are there any suggestions for this?
