Narrative:

Departing runway 24 teb on the ruudy 4; we crossed wentz intersection at 2;000 ft instead of 1;500. The incorrect altitude had been set. Upon checking in with ny departure we realized the mistake and departure issued instructions to descend to 1;500. Once at 1;500 we were immediately given instructions to climb to 6;000. In giving the instructions ATC said we needed to be more careful flying the departure. We noticed immediately followed by ATC instructions to descend. During taxi we were instructed to contact clearance delivery for a reroute. The reroute was quite different and required a fair amount of changes to the FMS. As we reached the hold short line tower immediately cleared us for takeoff. We did not take adequate time to brief the departure and misinterpreted the altitude. Never allow yourself to be rushed; especially after last minute changes given to your flight plan.
