What is the best way to plant them?
Should I remove the tegument or can I leave the "wings" ?

I don't know specifically about this maple, I've heard it recommended
that you do remove the wings from maple seeds. However, they obviously
propagate with the wings intact in nature, so it probably doesn't
matter that much.

Maples usually have to go through a cold winter before they will grow,
so you should either plant them now or put them in the refrigerator for
several months.
