Remember that you have a very long way to go. Your child isn't even at school yet. You have many years of him being in a class with a mix of children, and pot-luck with the teacher.
My daughter walked when she was just 10 months, spoke at 9 months, bilingually, swam at 1, etc. It doesn't always work that then they will need something extra or different at school. To be honest, the best you can do is to invest in a school with small classes and genuinely good teachers. Not just a name or a reputation. And you can't rely on the 'services' provided in mainstream schools. You need a place that really cherishes the individual. I've found one now (after a false start elsewhere). But remember that if a child is quick and makes connections, then they can very swiftly go to ground - hide their feelings, and even their talents, to protect their very sensitive emotions.
I was considered sub-normal at my first school, as apparently sat and said nothing. It was because I wasn't sure how to join in, as what they were doing seemed so simple and I didn't get it. I thought I was missing something. I won't go into it, but it turned out I wasn't sub-normal, whatever that may be (their term).
I would suggest you lay aside the advanced reading programmes and whatever other mechanical progress aids you have, and concentrate more on finding a first school that will support your child emotionally, and understand their sensitivity.
As I say, there are many years ahead. As a parent you too don't want to be put through the mill. My son, very musical as well as bright, used to copy the sing-song voice of the teacher. I was hauled in front of the Head for it. You need a place where the individuals dealing with your child have the intelligence and humility to respect you child's vulnerability and innocence, as much as anything else.
