Narrative:

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.
