I just don't want players to think I am calling them stupid, but at the same time I want it to be a questline where true beginner players can learn.
Then make it a questline where a true beginner is guided.
Just be careful of the order of things.
Want to work with people of different skill sets? Chapters.
Chapter one
This chapter assumes that you don't know the first thing about the mods.
Pre-reqs: None.
Passing: You know how to make string and silkworms from crocks.
Chapter two
This chapter assumes that you can make string, fishing rods, etc., but have never needed a cobble generator or automated block breaking
Pre-reqs: Crooks and silkworms
Passing: Can make a something to stuff a chest full of cobble with no attention on your part. Can hammer cobble to gravel
Chapter three
This chapter will show you how to automate full ore processing
Pre-reqs: Knowledge of sifters, hammers, autonomous activators, block places, and some form of piping (hoppers, pipes, etc)
Passing: Your supply of ores is fully automated.
Hmm, might need another chapter in there somewhere on piping.

What you really need, especially if you want to spread the quest development out over multiple people (hint hint ... forward this to the HQM people) is the ability to join two different sets of quests into a single book. So, different people can write different chapters / quest lines, and you can put it all together when done.

Order: I played AgSkies with no knowledge of the primary mods. And I mean *none*.
Crooks should have been the first thing taught, because of the importance. Having never had to make a cobble generator in the air before, my first two attempts were pure disasters, and I actually had to cheat (look up a layout online) to make one work. After about the 6th quest, there's 7? quests that open up all at once, and for someone that does not know what to do, that's too many, and attention is scattered. Even if it is the case that you could do any of them, keeping a beginner focused on what's most important -- and that was a modpack all about automation -- is critical.
Until you have automated production of sand, grout / tinkerer's construct should not even be shown on the quest lines.
And if automated sand is the key early thing to aim at, then aim at.
I had friends help me out when playing AgSkies. They explained the crook long before the questline did, and I was getting into string, and off the questline. I quickly realized that automation was the most important thing, long before automation was explained.
So, perhaps a better way to explain order: If you were to ask someone very knowledgeable, "What is the most important thing for me to do next?", what would they say?
