Those are most of the main quests currently implemented. However, based on the Rahi's work so far, there will be two more main quest chains added soon. There are other mods which add more content (See the Alex mod) but most do not compare to the original just based on scale.
Additionally, didn't see the lux and mirri quest chain on the list. It requires enslaving an NPC and ranking them up to level five then going to sleep to activate the first scene. Pretty good content and should take a while longer than the previous ones with having to rank up the black market through selling slaves in order to progress the storyline. Hope this helps!
