Montessori might be the way to go. Go and observe a classroom in action. Ask the recieving teacher what she does with children who are 'overly talkative.' It's quite possible that their self-paced materials will give him something to do besides read, talk and play with this this's teacher's minds. I don't blame him for setting for himself the interesting challenge of seeing how far he can push the teacher, but I wouldn't want my son left in an environment where his has to self-enrich in quite that way.
Have you tried that 'transforming the difficult child workbook' by lisa bravo? I see it as a way of 'saving kids the bother' of acting out in order to get their attention needs filled.
that 'feet off the table' thing sounds Oh So familiar. Cringe! But gratefully DS is now much more interested in getting postive attention for his many talents and strengths.
Good luck, whatever you do!
