Also, learn how to stick up for yourself, go after things you want, have some confidence, think positively, and interact productively with other people and you can do fine without having to be a jerk.
The quote, "An idle brain is the devil's workshop," comes from H.G. Bohn's "Handbook of Proverbs", published in 1855. Often, the word "brain" is substituted by the word "mind" and "workshop" is sometimes changed to "playground" in the modern daily use of the expression.
As Ferbin says, this refers to the game of "horseshoes" wherein you toss horseshoes at a stake in the ground. Those that land within 6 inches are scored - i.e. close counts.
Indeed: Nietzsche wrote “Aus der Kriegsschule des Lebens.—Was mich nicht umbringt, macht mich stärker,” which can be translated as “Out of life’s school of war—what doesn’t kill me, makes me stronger.” It appears in his book of aphorisms, Twilight of the Idols, and no further explanation follows.
Nietzsche expands on the idea in his autobiography Ecce Homo. (yep!)
In it he writes about certain individuals as “nature’s lucky strokes…among men,” and says about these people, “They divine remedies for injuries; they knows how to turn serious accidents to their own advantage; that which does not kill them makes them stronger.”
That's not its full context, it's two similar but separate sayings that have been remixed and mashed together over the years. "Imitation is the sincerest form of flattery" dates from at least 1820, with versions (e.g., "Imitation is a kind of artless flattery") dating back to at least the early 1700s.
"Plagiarism is the homage that mediocrity pays to genius" dates to 1842, with "Imitation is the homage which mediocrity pays to superiority" following close behind in 1851.
Versions of both are used numerous times over the next couple of decades, with a version combining the two ("Imitation is the highest compliment mediocrity pays to genius") showing up in 1874. Various permutations using satire, caricaturing, ridicule, etc., and tribute, homage, flattery, etc. show up many times over the years, with the form you quoted first appearing in 1999 (falsely attributed to Oscar Wilde.)

Hand grenades are self-explanatory, I hope.

Taking that one out of its full context waters it down.
