-Spider-Man fakes shots of himself fighting the Sandman in Amazing Spider-Man #4. His dialogue excuses this as like shooting an action replay.
-He fakes shots of himself changing into Electro in #9.
-JJJ admits to himself that he tries to tear Spider-Man down because he's jealous of him in #10.
-Foswell actually was the Big Man in #10. Jameson gave him a second chance later.
In “The Death March!” from Jimmy Olsen #76 Perry enters into a bet with another editor to prove the loyalty of his staff to the Planet. Their plan involves Perry’s leading Clark, Lois and Jimmy on a march through a desert in Civil War-era costume while heaping abuse on them.
I think you’ll find quite a number of Lois stories involve Lois’s being sent on assignment, doing something outrageous to get a story, or trying to catch a criminal for the story. Tales that leap to my mind include:
-“Lois Lane’s Other Life!” (Lois Lane #35, reprinted as “The Day Lois Lost her Mind!”), in which (from memory) she disguises herself as reporter “Sheila Dexter” to get an interview with a man she knows would refuse to be interviewed by her real self
-“Lois Lane, Super-Telepath!” (Lois Lane #56), in which she and Jimmy perform a mentalist nightclub act in order to get her abducted by a gangster as part of a scheme to capture him
-“The Amazing Hydro-Girl!” (Lois Lane #60), in which she drinks an experimental serum that allows people to breathe underwater so she can write about it.
Incidentally, it's easy to think of Lois Lane as an also-ran title, but according to the statements of ownership average circulation figures complied by John Jackson Miller at Comichron it was a top-selling title in the 60s: also, in the years in which it reported, the reporting female-lead title with the highest average tales (with Betty and Veronica just behind it in 1969). The reporting romance titles had lower average sales too.
In “Miss Jimmy Olsen!” (Jimmy Olsen #44) Jimmy disguises himself in drag and joins a chorus line as part of his investigation of a criminal.
In the first Olsen-Robin team story from World’s Finest #141 Jimmy and Robin don’t think Superman will believe them because of bum tips Jimmy has recently given Superman.
My recollection is Iris does some reporting in “The Man Who Mastered Absolute Zero!” in Flash #134. She goes to a jail to report on Captain Cold’s recent escape, and learns he’s now infatuated with a dancer called Miss Twist.

I have no clue as to what issue it was, but the first time I recall JJJ soliloquizing on his jealousy of Spider-Man was during Marv Wolfman's run as writer on Amazing. He and Spidey were chained together in some comicbooky way by Professor Smythe, the creator of the Spider-Slayer robots. Spidey kept his head throughout the ordeal while Jonah was freaking out, and after Spidey frees them both and saves the overall day. Jonah announces to himself that he knows he can never be the hero Spider-Man is, and that's why he feels he must ruin him.
This was in the 70s though, so it wouldn't fit the thesis as you describe it.
I would swear that Jameson/Spidey being chained like that occurred back in the Lee/Romita days, or perhaps a similar story. Also, I'm pretty sure Jameson had a monologue about his hatred of Spider-Man very early in the Lee/Dtiko run, in the story in which Spider-Man rescued John Jameson.
Specifically from the 1960's. I recall very little attention or effort paid to journalistic ethics. Certainly the prevailing attitude in the Superman Family books was whatever got you the story was okay.
