We got a lot more mileage out of the handful of emails my 2nd grader wrote to her teacher and principal last year than all the advocacy meetings my dh and I attended.
I agree with the previous posters that mentioning book titles rather than reading levels would be helpful. I assume that most teachers loved to read as kids, so if they know that there is a child in their class who likes to read really good books, there is a good chance of the teacher being inspired to differentiate for dc.
I also think it might be wise to leave out the perfectionism issue. You can always bring it up in a few months if you are still seeing it. I would worry that it might provide a reason for the school to avoid further accommodations - this doesn't make sense to me, but I have heard of this happening.
Good luck! I think its awesome you have already received your welcome packet. I know DD won't get her's until 4 days before school starts and its driving me crazy with all the "what if"s!
