OK, so here's the things that I was able to clarify today:
Dress Code: generally trying to model the students. So the student dress code applies to me as well (not an issue). Unlike most Steiner schools, where black=evil, this school understands that some items of clothing ONLY come in black for kids (i.e. tights) and just say a "miniimum" of black. The principal this morning had black pants on and the teacher of the class I'll be with had on a sweatshirt, jeans, a black apron and steel-caps
Parking: Again not a problem, they're quite happy for me to use the staff car park without needing a pass or permit or anything. The school is sort of "off the beaten track".
Classroom: I am with Class 3 (which is roughly Year 4). Although because said teacher is due to be a daddy

, we may end up with me doing half my placement in Class 3 and half my placement in another class. I am going to bring this up with my co-ordinator. At least the students can read!
Other things I discovered:
-Teachers are addressed by their first name.
-The sick room is called the "Wellness" room.

-There is no canteen on site, but if I need food and forgot to bring my own, there's a bakery up the road.
