I would say very little. I would mention the grade skip, as this will make the teacher aware that your child's abilities have been reviewed and assessed by others and they are advanced. Then I would write some stuff about how she has a baby brother and loves kittens or soccer or whatever fits her situation.
I like the idea of having your daughter write too. Make sure she signs with her first and last name.
I think it's fine to be pushy if the situation demands it, but I don't think this is the right opportunity.
