Simple Question for my build.. does the Caster level from harper paragon add to the healers temp HP max and radius of their circle and mass heal spells?

considering the class for Harper RP and detect evil.. the characters cha is 10 så its not for divine feats. the 2 feat investment is huge if the class dont fit well with healer's

This question was asked before about the interaction between paragon CL and evocation spells damage for sorcs, also PM cl and warlock elrdich blast and so on. I'm still not sure about the answer but I'm curious. One thing I know for certain is that the CL always adds in regard to resistance to dispels.

Radius - Yes, though might change.
Overheal - No, does not apply.
