Large transport aircraft overshot assigned altitude on climb by 300 ft and returned back immediately. Flight crew reporter's state that, because the course was not displayed and FMC programming required their attention, it contributed to a high workload and distraction from altitude.

Narrative:

Departed iah, we were issued a climb to 15000 ft, clearance was radar vectors to first fix. About 30 mi west, we were cleared on course and a frequency change. Due to the fact that the course prior to the fix was not displayed, this created too much of a workload with the EFIS/cockpit load. We had altitude deviation of 300 ft high and corrected back to 15000 ft immediately.
