as far as your professions... they're really up to you. you can do whichever you want with them because they all offer you some benefits that the others don't.... so that's going to be a matter of preference.
as far as your spec and gear go, it looks like your armory was cached with your pvp gear on, so it's hard to tell about things, but let me tell you what i see based on what you're wearing...
first, your hit rating is low.. regardless of what spec you are, your hit is low.. if you go arcane, you need at least 10% hit rating (since you're alliance and can count on a draenei in a raid). As frostfire you need another 3% hit to be hit capped.. that should be the first thing you go for.
as far as other things go, your wrists have no enchant on them, your belt has no crafted socket on it, and your boots should have icewalker on them (but i'm assuming your nitro boost is for pvp).. For your blade, I would seriously consider getting th mats together and having the titansteel spellblade
made, since it's more SP than the flameheart spell scalpel. I would also look into getting your wyrmrest rep up for the boots that they have (the name escapes me atm), as they will last you into naxx 25.
that will give you a huge increase in your dps right there by just doing those simple things.. again, i'm not sure if you have different pvp gear from pve gear, but i'm assuming you do.. i can only go off of what i see.
