I took the freedom to put together a BiS-list that you can obtain through money and emblem of triumphs + drops in heroic 5 mans. With this setup you can w/o problems heal the majority of the bsoses in ICC10/25 N/H.

Notes:
* Contains the crafted cloth-parts. If you are like some people allergic to cloth just replaced them with the mail crafted parts instead.
* I included the items you already have or will get.
* If you feel that the crafted parts/hilt will be too expensive you replace them with the following:
* I picked Shriveled Heart since it IS the best you can get as an offhand. If you would rather use a shield, stick with what you have.
* Forethought Talisman might have a nice SP-boost. But with the amount of haste in this set you want to have a nice manapool and nice mana regeneration. Hence the Tears of the Vanquished isntead of Forethought.
* Royal Dreadstone is being used in your head since it covers both a red+blue at the same time in the slot with the biggest socket bonus. That way you can pump out haste in every other slot.
Legging's of Woven death: Blackened Ghoul Skin Leggings.
Hammer of Purified Flame: Surgeon's Needle.
Bejeweled Wizard's Bracers: Could not find anything suitable to replace them with apart from the bullcrap Valor of Emblem's Wrists which is complete utter shit. Rather use what you already have if so.
Ring of the Darkmender: Heartmender's Circle.
I hope this helps but I doubt it since you already have the majority of the gear!
