Narrative:

Taking off out of pbi. I read back 7000 ft 250 KTS. Departure again gave me the whole clearance. We went through procedures (everything happening at once) when I hit 'climb 2' button computer did not switch over and remained at takeoff power. First officer thought autothrottles were malfunctioning. We were climbing like a rocket because we were very light (pbi-mco). I called 1000 ft to go but first officer was distraction and when I repeated 7000 ft, he pushed over we ballooned to 7500 ft which departure brought to our attention. This was a problem aggravated by another change of procedure, a non-standard departure and a flight system that was causing us more problems than it was 'lightening our workload.'
