Make me bad: Mage Edition

Once again, I find myself in the position of gearing up for raids, but this time there are far fewer crafted items to help me along. The good news is that I seem to be okay to at least start Naxx already, being as the requirements to successfully start it seem to be a lot less stringent than they were to start Karazhan. The bad news is that I have very few ways to upgrade certain slots before raids:

• Shoulders: except for the BOE from Naxx, which even if I were lucky enough to see on the AH anytime soon, should easily go into the realm of 5k gold, not too many upgrades. The new enchant for them is from Sons of Hodir, which I will need to grind to put on my crappy, crappy blue.
• Legs: Short of H. Halls of Lightning or H. Utgarde Pinnacle -- and we all know how everyone loves doing those -- again, not that many upgrades. I don't like giving up crit for more spellpower when I make absolutely no use of spirit whatsoever.
• Bracers: There are some decent ones from H. Oculus, but again, not too many upgrades. I need to put a spellpower enchant on the ones I have. They just seem almost not worth enchanting. I still can't get used to the sight of all these blues.

As for the cloak, I suppose I could get Loremaster of Northrend and craft the epic cloak with no stats, and enchant it with haste. It's really not a terrible idea, I need the money anyway. The headpiece can be upgraded with the engineering googles, but that will take a while.

For raiding I'll probably pick up Flask of the Frost Wyrm and some Succulent Orca Stew. I can hit cap FFB with just 2 gear switches, to cap out the other fire spells might not be possible right now. I'd like to shoot for 1400 spellpower, 30% crit, and 176 haste (which makes my FFB down to a 2.8 second cast).

Rotation is still a little bit up in the air. It will depend on whether I want to respec to get Living Bomb. I'm doing a solid 1.5k in heroics, which seems pretty standard for mages with no raid buffs. In Heroics, I find myself using scorch and fire blast a lot more than I thought I would. Sometimes you just don't have time to cast another FFB, and a Scorch/Fireblast combo is a good way to ensure death for a mob. Of course, ignite doesn't really do much for trash, but it's very good for bosses, or really anything that's up longer than a minute or so.

I'm also using the scorch/fireblast combo on a lot of mobility fights where I don't or can't stand long enough for 3 seconds (the last boss in Nexus, for example). It's suboptimal but better than death. Sometimes, if I'm lucky, it will proc the Hot Streak pyroblast for some extra damage.

To recap:
Enchants: Shoulders, cloak, bracers. New head enchant (might wait until later).
Hit cap: 289 (FFB), 367 (everything else). Soon this will just be a flat 367.
Consumables: Succulent Orca Stew, Flast of the Frost Wyrm.

I need better gems, but I can't afford them right now. Sigh.
