Narrative:

Pushed back from the gate with autothrottles deferred, and had a speed flag on the ADI. Stayed with ground crew and called maintenance coordinator, who had us start engines and pull and reset a thrust management computer circuit breaker, then make a write-up. By this time, 2 inbound aircraft were waiting for us to clear to access the gate area. Ground crew were still connected, but it had been 10 mins since we had seen or heard from them, and captain called for taxi clearance, which we got, then released brakes before salute and release from guidance. Immediately realized error and reset parking brake. Ground crew confirmed all was normal, disconnected, and gave salute and release. Debriefed thoroughly. Abnormal operations caused us to get out of sequence and pick up in the flow without completing the before taxi-out sequence which would have prevented this. Not being able to see the ground crew, and working maintenance problem with maintenance coordinator on radio made it very easy to forget they were still plugged in after such a long delay. Serious lesson learned.
