Narrative:

Teb SID for runway 24 requires fly runway heading until reaching 1500 ft; then turn right to heading 280 degrees maintaining 1500 ft until passing the teb 4.5 DME; then climb to 2000 ft. The cockpit/autopilot was set up for a hand flown departure to the 4.5 DME fix; then the autopilot would be engaged. The heading bug was set at 280 degrees; the altitude pre-selector was at 2000 ft. The set-up seemed reasonable; however; was not specifically briefed. Upon departure and passing about 1200 ft; the flying pilot engaged the autopilot (which is pretty normal) and immediately realized the aircraft started it's right turn prematurely. Resetting the heading control back to 240 was quick; but the aircraft was climbing to the 2000 ft selection. Maintaining control by autopilot; he pushed the manual pitch down rocker switch to stop the climb. The aircraft overshot the required 1500 ft by about 300 ft. I observed a newark arrival aircraft south and above our position; not in a conflict situation. I; as captain; should have required a takeoff briefing from the flying pilot. In addition; I learned not to set the altitude pre-selector higher than the cleared altitude for your current position; regardless of whether the autopilot is engaged or not!
