check out my gear please and let me know how i should spec my talents and what rotation i should be using for tier 5 content raids?

ive been looking into alot of mage theorycrafting and it just looks like fire IV spec is best...just wondering what i can do to up my dps as much as possible with the gear i have.

i would also like to ask..if anyone knows or has an opinion about....

should i go frost/arcane meditation for this level content considering i can replace Hit rating gems and enchants with spll dmg and haste gems n enchants? bc only 126 is needed for frost and 164 for fire....just wondering.

Scorch x5 then Fireball, and recast scorch 4sec before the debuff runs out.
Don't socket haste instead of crit until you can get around 150 haste rating and 30% crit by your gear alone.
0/40/21 for single target dps, 2/48/11 for single & aoe, although there isn't much aoe to do in t5 instances, you will need the aoe power when you will start Mount Hyjal.
The lightning bolt trinket is horrible.

instead of the T4 Hands use these -> http://www.wowhead.com/?item=34938

What about warlocks ?
About the spec is basicly the same for all destro locks, but i was wondring about mt gear, gems and if there is anything i should be replacing or focusing on :D
this is my armory link:http://eu.wowarmory.com/search.xml?searchQuery=megadie&searchType=characters
Also i would like to add that i have 107 haste raiting on this gear ( which don't appear on the armory ), and btw, i know my crit % sucks :P
My best dps i reached with this gear was 1627 dps, is that enough or i can get more out of it ?
Thanks for having the time to read my post.
Regards..

Sorry for the link, this is the right one:
