This is not a full explanation or tutorial, but merely an addendum to your understanding of setting up companions. There are some issues involved with an attempt at setting up a companion with the same limitations of the vanilla companions.
I highly recommend creating your own companion as way to familiarize yourself with these features of the GECK. Creating custom companions has been a boost to my understaning about the use of Quests to handle dialogue, AI Packages and how to use conditions in relation to those things.
