Question on editing an ability from someone clueless on mods

I've been playing through with a bunch of mod kits and wanted to edit the Dragon Disciples breath weapon to match a different bloodline (doing an all mage/sorcerer play through and having more variations between them is always nice). The Tome and Blood mod adds bloodlines and I can add the Breath Weapon ability back into the kit easy enough with EE Keeper. But I would prefer if I could match the damage type, for example I would like Acid damage instead of the default fire. Also (of lesser importance) change the graphic so the effect color matches the damage type. Is there a how to on this type of change posted anywhere here? Again I have never attempted to mod anything. Thanks in advance.
