Teenysteaney,
My DS, now 14, has a lot of the same challenges your son has (possibly more severe in some areas). What has worked well for us has been homeschooling with accommodations and curriculum modifications (acceleration in areas of strength, additional instruction and support in areas of weakness) and intensive OT,PT, and vision therapy with home involvement in all therapies.
As for the "He has to go to school to learn social skills." argument that is often thrown at us, his OT suggested and we found to be true that it was better for our son to be able to practice developing his social skills in settings where he was not also being asked to overcome all of his other physical and academic challenges simultaneously. He practiced social skills in social settings, like group movie nights, park play days, book, theater, and chess clubs, going to the store, attending religious services, going to parties, running around on the lawn with the neighbors, and other non-academic social settings. He practices and acquires academic skills in settings that are designed to minimize the impact of his disabilities on his academics.
We have also found that other gifted kids are his preferred social peers, and that he is much less anxious and comes across as socially much more "normal" in a gifted peer group than he does in an age-peer group where no one understands what he is saying or gets his jokes.
It is a tough road ahead, but I can tell you that it is possible to go down it with a measure of success.
Good luck as you go forward.
