After taking off out of TEB the Captain commanded me to put gear up. Then 400 FT asks for flaps up; LNAV; at the same time Tower told us to switch to Departure; while all that was taking place; our TCAS had a guy in front of us about a mile or two away. While we both were looking for the traffic and cleaning up the aircraft I (First Officer) did not hit the LNAV button and we did not level off at 1;500 FT. We noticed it at 1;700 and then descended to 1;500 FT. No problems were encountered.
We briefed the RUUDY 4 departure using LNAV/VNAV on the FMS and set the altitude alert for 2;000 FT. With flap retraction I called for MAN SPEED 200; VNAV. We received a TA. I asked the pilot not flying if he saw the traffic. With the distraction he had pushed FLCH instead of VNAV and the aircraft exceeded 1;500 FT prior to WENTZ. My excursion may have exceeded 1;700 FT. My pilot not flying has about 100 hours or less in type and it's the first jet he's flown.
A G-IV departed on the TEB RUUDY 4. During the climb; the newly trained First Officer; distracted by a TCAS TA; mistakenly hit Flight Level Change instead of VNAV which caused the aircraft exceed 1;500 FT before WENTZ.
