One of the big accommodations that's really helped my son (because of his PDD-NOS & ADHD) is preferential seating near the teacher. This allows him to quickly and quietly lean over and ask for additional instruction/reminders/clarifications throughout the day. I would definitely recommend you ask for that - it's probably the easiest accommodation to get them to approve and can be incredibly helpful.

Also note, you can call a new ARD meeting to alter the accommodations AT ANY TIME.
