Looking for tutorials which deal with changing and extending a Vanilla

Edit: title got cut off: "..extending a Vanilla quest with CK"

I've looked around and found many tutorials that deal with quest creation from scratch, but not any that deal with editing quests already in place. Know of any? I prefer video tutorials but text/other media are good too.

Specifically, I want to change the solitude opening quest. What I think is the relevant "quest" is found here: Object Windows > Character > Quest > Dialogue > Haafingar > Solitude > SolitudeOpening (all the way at the bottom). It has lots of stages, each with papyrus fragments that I don't really understand since they have relatively nonspecific seeming references. I don't really know where to begin with that. Here is what I want to happen: The player can enter Solitude normally, watch the execution happen, grab the amulet of talos and return it to Roggvir's sister, just as in Vanilla. Alternatively, the player can interrupt the execution and allow Roggvir to run away. The player can actually do this in Vanilla, but Roggvir is dumb and just runs around Solitude until he is killed and doesn't interact with the player at all. I want to make it so that Roggvir runs out of Solitude to Dragon's Bridge if enough diversion is provided by the player. I may choose to extend the quest past that.

Thanks in advance for any suggestions.
