I did this with rather lack luster gear (1 week into 60)  and all the recommended consumables. 
 A few things not mentioned and if the op can insert it into the - excellent- guide.
Spec into spirit tap, yes it works and after the first wave of skeletons spawn it will be up 90% of the time.  This will double the spirit elixirs/spirit buff/spirit scroll x2 as well as increase mp5 gains from spirit by 6.6x
Additionally it will grant you that much more +healing, which is needed since you may drop the +10% healing talent.
Blessing of Nordrassil is a buff the quest giver grants when she heals the peasants entering the light.

This is the spec I went with, 
http://db.vanillagaming.org/?talent#bxMrsVZfxtcb0VZxSince all I casted was FH rank 4, renew 6 and abolish this spec gave me all i needed.  I never casted PWS because me gear was so subpar it took to big a chunk of my mana pool.
Notice I dont have the spirit buff.  I did this fight with only a druid buff, oil, mp5 food, intellect elixir, and a spirit scroll as buffs.  If you follow this guide and get the all the buffs and consumables you set yourself up right.  I did this with 5k mana prebuffed, +200 healing, and 35 mp5 from items.
Good luck and follow the guide!! SPEC SPIRIT TAP = win!
