How about
this? I think improved Inner fire is now worth taking: you get 120 (base) + 54 (improved) = 174 spell power from it. And in a pve content you should have it always on. I think it's better to always have 174 spell power than to have +6% healing on a dying target (<50% life). So probably no "Test of Faith" for me...
Light well is much better than before, but it still takes disciplined people to use it.
And I'm not a fan of Inspiration. I think after a certain value the gain from the 25% armor is negligible.
Spiritual Guidance? 25% of all the spirit you might gain... If you will only have 400, you'll get 100 spell power. I think we'll have more likely more than 600, so that is 150 spell power. Also, if you get the IDS buff, you'll gain 80+20=100 more spell power. So just from changing some talents, you have a potential of gaining ~300 more spell power at level 80. And it scales with gear. The more spirit, the more spell power (and mana regeneration).
