Shadow priest 70 (DPS)

I'm not used to blog in English but as I'm linking half of the wowhead it was polite thing to do for those who may get here via WoW.

Shadowpriest benefits most from spell damage (and healing) therefore I linked the items we(I) should get pre-Karazhan (except for one ring). I'd like to add that many items obtained trough PvP (and some via Badges of Justice) so it should be doable for anyone considering grinding battlegrounds on a weekend should result minimum 10k honor (Alterac Valley for alliance (or horde if it is an AV weekend), all other battlegrounds for horde).
Two of the listed items is Aldor however I thin the Scryer version may be better for a dedicated shadow priest).

You can ignore the order of the items because I grouped them by source. Of course if you have access to arena items or the season 3 is passed you should take the better (S2+) item instead of the one listed.
The full list of the items can be found here

Carved Witch Doctor's Stick	25 badges	blue socket
Khadgar's Knapsack	25 badges	Have better (51 shadow damage) but I consider the healing as well
Cloak of Arcane Alacrity	60 badges	+haste and resilience
Fused Nethergon Band	60 badges	+spell hit
Icon of the Silver Crescent	41 badges	damage increase on use
Battlemaster's Audacity	75 badges	or get the version for honor and marks
Merciless Gladiator's Spellblade	25.200 honor and 20 Eye of Storm Mark of Honor	The arena version is better
Veteran's Dreadweave Cuffs	9.435 honor and 20 Warsong Gulch Mark of Honor or 25 badges	The arena version is better
Veteran's Dreadweave Belt	14.280 honor and 40 Arathi Basin Mark of Honor or 40 badges	The arena version is better
Violet Signet of the Archmage	reputation with the Violet Eye	This item needs you to run Karazhan and upgrades available.
Shattered Sun Pendant of Acumen	23g and reputation with the Shattered Sun Offensive	You will have the reputation pretty fast as you will do the daily quests for the money anyways.
Glyph of Power	100g and The Sha'tar - Revered
Greater Inscription of Discipline	8 holy dust	Do not buy the smaller version of this.
Enchant Chest - Exceptional Stats	4 large prismatic shards, 4 arcane dust, 4 greater planar essence
Enchant bracer - Spellpower	6 large prismatic shard, 6 primal fire, 6 primal water
Enchant Gloves - Major Spellpower	6 greater planar essence, 6 large prismatic shard, 6 primal mana
Runic Spellthread	Rune thread, 10 primal mana, 1 primal nether
Enchant Weapon - Major Spellpower	8 large prismatic shard, 8 greater planar essence
Runed Ornate Ruby	6.885 honor points	unique equipped
Runed Crimson Spinel	Magisters' Terrace (normal) quest	unique equipped, do not waste it for low level gear.
Ember Skyfire Diamond	Auction House or you can make one if you are Jewelcrafter	The Imbued Unstable Diamond is an option for your PvP gear but requires 160 Apexis Shards AND requires you almost a raid to do the quest which let you talk to the vendor.
