Did the people evolve on this planet or come from elsewhere?
They are indigenous to the planet.
Is there a written language?
Yes. It's mostly swirls and dots and looks similar to 'Elvish' and 'shorthand'. It's very graceful to look at but hard to decipher if you aren't accustomed to it.
Are different groups of people educated separately?
Is there a class system? Different levels of citizenship?
Yes. There is a caste system and it's easiest to recognize the members of each based on what, and how much, they wear.
