I have a character with variant tiefling ability #49

You are healed by both positive and negative channeled energy.

Several spells state "you channel xxx energy" or "if you are healed by negative energy then this spell heals you"

Now by RAW how would the following spells affect me? What can I use to heal myself?

Inflict wounds

Chill touch

Harm

Repair undead

Channel energy to harm living

Channel energy to heal undead

Bonus points : My variant tiefling ability was selected to match my characters design. My character utilizes several necrografts (undead bodyparts and limbs used to replace missing or healthy parts) while this does not technically make me undead, it dulls the effects of positive energy as well as giving me other undead like benefits. How would you rule the same set of spells for someone stradeling the line of life and undeath?
