I acknowledged a reserve trip the evening before and went to bed. I was then woken by a two hour call-out for a different trip that pushed in less than two hours. I arrived at the gate to find the aircraft boarded and the Captain completing the walk around. He started the ACARS and FMC duties as I settled in and ran my flows. We [reviewed] the route and briefed the departure and other normal items and pushed back. As I did the After Start Flow; I noticed the transponder had no code in it. We had no clearance. I had not done it myself and we did brief the route. I called for the clearance; we reviewed it and started the taxi. At that point there was no [Set Takeoff Flaps] call and no prompt for the Before Taxi Checklist. We moved a very short distance when I noticed the mistake and began corrections. We set the brakes at the hold short line; ran the checklists; called for departure; and completed the rest of the flight normally.Don't board aircraft without Crew Members present. It creates pressure on all to perform extra to help out. Unfortunately it leaves gaps in the duties; and items can get skipped.
First Officer was called out on reserve for early morning push. Scheduling woke him up and moved up his report time two hours. He arrived five to ten minutes prior to push. I had tried to complete all of his tasks. He briefed the departure which I interpreted as the clearance. We pushed back and realized as the Push Crew was departing that we did not have a clearance. First Officer got clearance and we called for taxi. Within about 100 ft; we realized that the flaps were not set. Set flaps; did all checklists. No conflicts or problems.Scheduling should not move an assignment up earlier in the early morning for a reserve. That puts both of us in a bad spot. This forced me to do two jobs and forced him to rush to work after being woken up two hours sooner than his alarm. Although I emphasized that we were not going to hurry; we still missed the clearance which led to missing putting the flaps out at the correct time.
