Concerned about money, Junior Soprano meets his nephew Tony at his doctor's office, asking for more help for his medical and legal expenses. Tony has his own expenses and angrily tells Junior to manage his affairs better. Later, Junior promotes Bobby Baccalieri. Assemblyman Ron Zellman tells Tony that Junior owns a property in a special development district in Newark which is going to rise in value. Tony buys the property, pretending that he is doing his uncle a favor. He also calls a meeting with the family's capos in which he harangues them about the zero growth in business.

Carmela is worried about money, having seen the widowed Angie Bonpensiero working at a supermarket. Tony insists that she and the children will be provided for if anything happens to him, but will not give details. He also claims money is no longer being hidden in their house, but later hides packets of banknotes in a tub of duck feed; Carmela happens to pass by just after he closes the tub.

Paulie Walnuts has been arrested in Youngstown, Ohio, on a gun charge, and resents Tony's apparent indifference. From a jailhouse payphone he calls Lupertazzi family underboss Johnny Sack, who is cultivating his dissatisfaction.

Ralphie Cifaretto and Janice Soprano are growing closer. Ralphie comes to a Sunday dinner at Tony and Carmela's home with Rosalie Aprile, but Janice later joins him in the bathroom for cocaine and sex.

Christopher, believing that Tony is treating him harshly because he questioned his action against Jackie Aprile, Jr., is using heroin again. He complains about the constant presence of Adriana's close friend Danielle, who is actually undercover FBI Agent Deborah Ciccerone. Adriana takes Danielle to Tony's home and introduces her to him. Junior hears that there was an FBI agent in his doctor's office. He realizes it must have been the nurse he was flirting with and is mortified that he failed to suspect her.

Speaking to Dr. Melfi about business with unusual frankness, Tony discusses his plans to use Christopher as a proxy in order to avoid jail time or death. In an attempt to bond with Christopher, Tony gives him the name and home address of a recently retired policeman who Tony claims killed Christopher's father. Christopher goes to the man's home and kills him.

• The episode's title is taken from a phrase found on American paper currency: "this note is legal tender for all debts, public and private". The episode ends with a close up of a twenty-dollar bill that Christopher takes from Lt. Barry Haydu after he kills him—the only episode in the series to not fade to a black screen.

• This episode was the first to be produced and aired after the September 11, 2001 terrorist attacks. From this episode on, the shot of the World Trade Center towers in the opening credits is absent, replaced by additional shots of industrial scenery before reaching the toll booth.
• Vince Curatola (Johnny Sack) is now billed in the opening credits, but only for the episodes in which he appears.
• A comment made by Carmine Lupertazzi to Tony Soprano, "A don doesn't wear shorts", was added into the show after series creator David Chase was contacted by a supposed real-life mafia associate who praised him on the authenticity of the show, with the exception that Tony often wears shorts, which he said a real don would never do.
• "For All Debts Public and Private" is one of only two Sopranos episodes in which the end credits roll on top of a picture (the eye of the twenty dollar bill in this case) instead of a black background (the other episode is "Cold Cuts" from Season 5) and the only episode in which they do so for the entire duration of the credits.
• Haydu was proven to not be responsible for the murder of Dickie Moltisanti in The Many Saints of Newark

• Bobby Baccala mentions the September 11 attacks in 2001 as a factor of his 69-year-old mother's deteriorating mental health.
• Bobby subsequently claims that "Quasimodo predicted all this", mistaking The Hunchback of Notre-Dame's main protagonist for Nostradamus, whose supporters believe accurately predicted many major world events.
• Junior is shown watching the movie Heaven Knows, Mr. Allison.
• During the scene in which Carmela approaches Tony about finances, the movie playing on the television is Rio Bravo, a 1959 Western starring John Wayne, Dean Martin and Ricky Nelson. In the scene that Tony is watching, Martin and Nelson sing a duet, "My Rifle, My Pony and Me". This song is also used at the end of the future episode "Pie-O-My."
• At Lt. Haydu's house, Chris is shown watching the Magnum P.I. episode "No More Mr. Nice Guy."
• When Paulie is on the payphone in county jail, The Jerry Springer Show is seen on the television in the background.
• During the scene in which Janice and Ralphie are snorting cocaine in the bathroom, Janice comments "Oh Bartleby, Oh Humanity" a reference to the drama surrounding Jackie Jr.'s death. This is the last line from Herman Melville's short story "Bartleby, the Scrivener."

• The song played at the episode's beginning and over the end credits is "World Destruction" by Time Zone (with John Lydon).
• The song played while two women make out on a hotel bed is "Do You Wanna Get Heavy?" by Jon Spencer Blues Explosion.
