Irena,
DS gets pull out OT I think once a week. His Therapist has been his classroom to observe and also to work with him. But it's never been subject specific as far as I can tell. There have been times where teacher asked for this so she could get OT's take on something he was doing. And I believed they used it to figure out what he needed assistance with.
I can't speak to the meeting issue - our only big one was the first, everything since has been with the teacher and OT but that's because they are not oppositional.
As for the typing, it was very sporadic and just a program for him to use in 1st. So he was very slow, hunting and pecking. So between 1st and 2nd during the summer he did typing twice a week for an extended period of time using the iPad app typing fingers. It made a big difference for him in 2nd, he is much better at typing and it's a much more useful tool than it was..
HTH,
