Thanks for the ideas. I think the issue of prioritizing among stimuli
could be an issue with him, I know its that way sometimes for me -
can't really deal well with two people asking me for things at once,
and if there is music on - then I really can't deal with it.

We started the chart this week and so far so good, he always does
better when there are clear goals and consequences involved. The
question is could he sustain this without a chart...
