Excellent advice from everyone here.
Indeed.
I'd like to add a couple things:
SMV has two excellent quest rewards.
[wowitem=30925]Spaulders of the Torn-Heart[/wowitem]
and
[wowitem=31104]Evoker's Helm of the Second Sight[/wowitem]
Neither of the quests are too awfully hard if you can get a group for the group parts.
Additionally, I'd recommend a crapload of SV runs as well for gear to tide you over until you get your spellfire/spellstrike. Includes a robe and belt with +hit, which is good for raiding, as well as other items such as a ring and your mage set gloves and shoulders(good, not great). And if you do that place enough, you'll get exalted with CE. That gets you an awesome epic ring with damage and spell hit.
Finally, I'd like to recommend a resource I use to help me plan out my gear goals from instances.

That site will help you see everything from every instance in both regular and heroic mode that may be of interest to you, as well as blues from quests to look to get. Seriously, check it out.
