It sounds like you've taken the most difficult steps already (getting all the teachers and psychologist working together)... and have met with great success (an IEP in the works), so you should definitely be proud of the progress you've made in getting your son the accommodations he needs at school. Of course, you will always feel like you can do more... so here are a few ADDitude articles that might give you ideas for starting off the next school year right, for making sure that IEP is rock solid and for keeping it that way over time...
