Summer jobs are a rite of passage. Time for maturing?

And this year, I kind of got the greatest one. I became musical super girl and flew through every summer night.Travelled every night?

Living a life that would make most mothers weep.
Three trusty boy sidekicks, no chores, and a bus full of empty calories. A bunch of hungry people?

When it was quiet, musical super girl just plain couldn't believe her luck. It was too good to be true?

Because most girls would love this job. Most girls would never want to come home.
But they'd be wrong, because coming home was the sweetest part of all.

Yes, pretty much. See http://idioms.thefreedictionary.com/a+rite+of+passage : "an activity or ceremony that shows that someone has reached an important new stage in their life, especially the start of their adult life"

Not very easy to interpret. Could it refer to a stage show in which she appeared to fly through the air like superman? Or, perhaps it just means that the nights passed quickly and pleasurably.

Food high in calories but of low nutritional value.

She couldn't believe how lucky she was. "plain" emphasises how hard she found it to believe.
