Am I correct in assuming that to acquire any of the Master Crafter's books beyond level I (and maybe level II) one can only purchase these with yellow crafters scripts?

If this is so, then I have to figure out how to obtain these scripts if I want to progress with crafting at higher levels.

I have completed the "Inscrutable Tastes" quest. And Zhloe Aliadoh tells me that I have to give here something called a "near eastern antique". (I also think this is what I have to provide by gathering and that perhaps there are different items I have to get for each specific craft). But I am not sure this is correct. She provides additional information which I do not understand. For example, if I am not level 80, I cannot gain white scripts, only experience. I don't know anything about white scripts, why is she telling me this?

She also tells me I can purchase what I need to craft collectables from a material supplier in Idylshire's Freewalks Roundspot. I go there, (5.9, 7.1) and there are about half a dozen NPC's there but I do not see a "material supplier" and none of the others will sell me anything to help me craft whatever it is I have to craft in order to obtain some yellow scripts.

Is has to be pretty obvious by now to anyone who has read this far that I really have no idea how to go about obtaining yellow scripts.

I have completed quests for my Alchemist to the point where the current request states that I have to provide three items which can only be crafted once I possess the Masters Alchemist Book III.

If someone who does know how to get yellow scripts could help explain the basics to me, I would appreciate it.

I just need to understand how to go about it all.

Thank you for your help!
