I heard you were looking for some mage advice and critiques.  Your armory currently has you spec'd frost, so the following gear suggestions will be based on that spec.

Your "to do" list at this point, in rough order of priority, is:

1. [Sorcerer's Alchemist Stone] (BoP Crafted) would replace the Bloodgem
2. [Tormented Demonsoul Robes] (Badges) + Restore Mana Prime Enchant
3. [Belt of Blasting] (BoE Crafted)
4. [Boots of Incantations] (Badges) + Boar's Speed Enchant
5. [Spellstrike Pants] (BoE Crafted) + [Runic Spellthread] (Crafted)
6. [Spellstrike Hood] (BoE Crafted) +
   [Glyph of Power] (Sha'tar Revered)
7. [Enslaved Doomguard Soulgrips] Badges
8. [Carved Witchdoctor's Stick] (Badges)
9. Get to Exalted with Scryers for [Greater Inscription of the Orb]
10. [Scryer's Blade of Focus] (Badges) + Soulfrost Enchant
11. [Fetish of the Primal Gods] (Badges)

That's alot of badges, but it's good gear - some of which isn't replaceable until Deep BT or Sunwell.

I notice on the parses from last week's Gruul/Mag that your were fire.  If you are planning on gearing up fire over frost for PvE, let me know and I can revise your gear suggestions.

As far as your performance as fire spec, I only see one thing that would concern me.  Your ratio of Scorches/Fireballs seems off.  Too many scorches for the number of fireballs.  It can be rough, since you were the only fire mage there.  Two tips I would give:

1. Refresh scorch early if you're about to have to run.  (Cube lciking on Mag, ground slam on Gruul)  It has a long enough duration that if you can get one on right before you have to run out, it should be able to last til you get back.  Having to restack the full 5 every time, especially by yourself, will cost you ALOT of dps - possibly more than just going without depending on the intervals.  This will come easier with experience.  If you're frost, you have a similar mechanic with stacking winter's chill, but seeing as how it's just attached to the primary nuke anyway, it's usually easier to deal with.
2. Don't bother scorching on trash in 25-mans unless the mob has more than ~125k hp. (At the time you start attacking it).  You end up spending too much cast time on scorch's lower dps and never getting the real benefit since the mob dies by the time you get your first fireball or two off.

Regarding frost:  Blizzard still has not fixed the "ghost hit" issue with frost.  Basically there was a strange issue, seemingly with the Elemental Precision Talent, that gives frost spells 6% hit instead of the advertised 3%.  This means that for Frost, you only have to stack 126 spell hit to be capped, instead of 164.  Keep this in mind as you plan your gems.
