Oh well... it's been a while since I visited the cloth items in the vote shop, so bare with me here.
First of all grab Show of Faith as a trinket. 2nd one, possibly because you are still gearing up, mana might be an issue, I would grab Sif's Remembrance. When you can, try to switch this to the toc25 one, or the eof one.
Since SP is the main stat, I would recommend grabbing all the 239 ilvl clothes (of course the healing ones, so no hit rating). If you were to run out of points around here, then prioritize the ones w/o spirit. If there is no item with 239, then go lower on the ilvl, but note that these ones are usually easily farmed, and thus not worth spending points on.
As a cape, your best bet might be Drape of the Sullen Goddess.
The MH+OH combo is Constellus (mace) and Shivered Heart.
For the neck, the 232 ones are better, but these ones you can farm in toc10 mans.
Your best bet as a ring might be Starshine Circle, but I think you would be better off grabbing the Dalaran one.
In my opinion the most important ones to grab are the trinkets, possibly the weapons. If you can, grab a battered hilt, and don't spend the points on a MH weapon, since BH is good to go till the ICC gear levels.
