Reporter encountered 757 wake turbulence and wind shear on liftoff, had a noise abatement climb to 1500 ft, and a problem contacting departure all of which he asserts contributed to his missing his 2500 ft leveloff.

Narrative:
After a long ground delay, we departed shortly after a B757. Encountered moderate wake turbulence mixed with wind shear right after liftoff. The first officer was having a hard time contacting departure control because the wrong frequency was given in the clearance (119.2). The SID calls for 2500 ft but with all these distrs and anticipating a higher altitude from departure control I ended up going through 2500 ft and initiated a level off too late. Our altitude reached 3000 ft by the time I could get the aircraft nosed over and back to 2500 ft. Shortly thereafter the first officer was able to establish contact with ewr departure control and a clearance to 6000 ft was given. I believe that the SID at ewr (4L in our case) has the cockpit crew too busy right after takeoff. With noise abatement, clean-up begins at 1500 ft, shortly thereafter is the level off altitude. Combine this with all the required turns, add in some turbulence late night, etc, and it opens the door to a mistake. I think that at the least, the altitude on the ewr SID's should be raised at least another 1000 ft so that we have more time to stabilize our takeoffs.
Original NASA ASRS Text
Title: RPTR ENCOUNTERED 757 WAKE TURB AND WIND SHEAR ON LIFTOFF, HAD A NOISE ABATEMENT CLB TO 1500 FT, AND A PROB CONTACTING DEP ALL OF WHICH HE ASSERTS CONTRIBUTED TO HIS MISSING HIS 2500 FT LEVELOFF.
Narrative: AFTER A LONG GND DELAY, WE DEPARTED SHORTLY AFTER A B757. ENCOUNTERED MODERATE WAKE TURB MIXED WITH WIND SHEAR RIGHT AFTER LIFTOFF. THE FO WAS HAVING A HARD TIME CONTACTING DEP CTL BECAUSE THE WRONG FREQ WAS GIVEN IN THE CLRNC (119.2). THE SID CALLS FOR 2500 FT BUT WITH ALL THESE DISTRS AND ANTICIPATING A HIGHER ALT FROM DEP CTL I ENDED UP GOING THROUGH 2500 FT AND INITIATED A LEVEL OFF TOO LATE. OUR ALT REACHED 3000 FT BY THE TIME I COULD GET THE ACFT NOSED OVER AND BACK TO 2500 FT. SHORTLY THEREAFTER THE FO WAS ABLE TO ESTABLISH CONTACT WITH EWR DEP CTL AND A CLRNC TO 6000 FT WAS GIVEN. I BELIEVE THAT THE SID AT EWR (4L IN OUR CASE) HAS THE COCKPIT CREW TOO BUSY RIGHT AFTER TKOF. WITH NOISE ABATEMENT, CLEAN-UP BEGINS AT 1500 FT, SHORTLY THEREAFTER IS THE LEVEL OFF ALT. COMBINE THIS WITH ALL THE REQUIRED TURNS, ADD IN SOME TURB LATE NIGHT, ETC, AND IT OPENS THE DOOR TO A MISTAKE. I THINK THAT AT THE LEAST, THE ALT ON THE EWR SID'S SHOULD BE RAISED AT LEAST ANOTHER 1000 FT SO THAT WE HAVE MORE TIME TO STABILIZE OUR TKOFS.
