What are some of the literary elements used in Alexie's "What You Pawn I Will Redeem"?

Sherman Alexie's story "What You Pawn I Will Redeem" is a brief sketch of two days in the life of Jackson Jackson, a Spokane Indian who has seen his grandmother's powwow regalia in a pawnshop, and is trying to scrape together the money to buy it from the pawnbroker.
There are many literary elements at work in this story, so I've picked the most fundamental to focus on. I'd invite you to consider others, as well, particularly Alexie's use of language and point of view to create Jackson's reality, both as Jackson sees it and as people outside Jackson see it.
The main setting is the city of Seattle, Washington, and within that frame are several individual settings, including:
the city streets, which Jackson walks every day, begging a little money here and there.
the pawnshop where Jackson finds his grandmother's regalia.
the alley beneath the Alaska Way Viaduct where Jackson and his friends drink themselves to sleep.
the office of the homeless charity, Real Change, for whom Jackson sometimes sells newspapers.
the Korean grocery store, where Jackson buys lottery tickets.
Big Heart's bar, where Jackson spends all the money he won with the lottery tickets on buying drinks for the bar patrons.
The main character is Jackson Jackson, who narrates the story in the first person. Alexie deftly sketches several other characters that Jackson either already knows or meets throughout the course of the story, including:
Rose of Sharon and Junior, Jackson's homeless friends, whom he calls his "crew." Rose and Junior both leave before the story is over, but Jackson is used to people coming and going, and doesn't seem overly surprised.
The pawnbroker who has Jackson's grandmother's regalia in his shop. The pawnbroker is a fair and honest man who offers to sell Jackson the regalia for the same price he himself paid, almost one thousand dollars. Jackson is unable to come up with the money, but the pawnbroker gives him the regalia anyway.
Irene Muse, a woman at Big Heart's bar with whom Jackson has a brief sexual encounter. She is friendly, funny, and attractive. Her friend, Honey Boy, is bisexual and flirts with Jackson throughout the evening.
The Big Boss at the Real Change office, who gives Jackson fifty newspapers for free to sell to try and come up with the money to purchase the powwow regalia from the pawnbroker.
Officer Williams, the generous and kind-hearted cop who has known Jackson for many years, and picks him up off the railroad tracks the morning after Jackson's night at Big Heart's. Officer Williams wants Jackson to have a good life, but he doesn't really judge Jackson for living the life he lives. He tries to help him however he can, and Jackson considers him a friend.
Jackson's grandmother, Agnes, whose powwow regalia is hanging in the pawnbroker's window. Agnes was a nurse during World War II. She was funny and strong, and Jackson loved her very much. She died of breast cancer when Jackson was young, and Jackson wants to get her regalia from the pawnbroker to reconnect with her, in a way.
The plot is very simple: Jackson wants to get his grandmother Agnes's powwow regalia from the pawnshop, but he does not have the money to redeem it. The pawnbroker offers to hold the items for twenty-four hours while Jackson gets the money together. Jackson spends the next twenty-four hours wandering the streets of Seattle, getting drunk with his friends, encountering various other people and sharing his story with them while hearing their stories in return. He periodically gets a little money—five dollars here, twenty there—but he immediately spends it on himself and his friends, even strangers at the bar. When the twenty-four hours is up, Jackson still doesn't have the money to buy his grandmother's regalia, but the pawnbroker gives it to him for free. Jackson is overcome with the man's kindness, and dances in the street for joy.
The theme is a bit harder to articulate, but I would posit that a theme in the story is human kindness. Jackson's life is rough, he has no shelter, he must beg to get enough money to live, and he never manages to have enough money to get out of his situation. And yet, Jackson seems happy. He meets everyone with an open, generous heart, and the people in the story respond to him in kind. Jackson appreciates every small thing that comes his way, and he wants to share his happiness with everyone around him, through food, liquor, money, and general goodwill. Although Jackson can't organize himself enough to "clean up his life," it almost doesn't matter: people are good to Jackson, because Jackson is good to people. He gets through each day, every day, and the details are negotiable.
