To leverage the +30 Light spell power from Morninglord, I was thinking of a mix of Divine Disciple and Angel of Vengeance - take either 4 Cleric levels for the SLAs/spell power/crit chance, or 5 FvS levels for the spell points on crit/crit chance/caster level, and then the remaining levels in the other divine class (with possibly a 2 level splash for survivability).

I suspect I know the answer to this, but if I have Nimbus of Light (for example) as a Cleric SLA and a FvS spell, is my SLA caster level for it still my Cleric level, rather than my FvS level or character level? If so, that would push me to go 6 FvS (aura), and 14 Cleric (or 12 Cleric/2 Monk; are the goodies from two Monk levels worth giving up level 7 spells?), rather than the FvS12/Clr6/Pal2 (or Fvs14/Clr4/Pal2) I was considering.
