As regards point 1: "Freud cites libido as the driving force", Freud separates libido from the will to power:
libido has the task of making the destroying instinct innocuous, and it fulfils the task by diverting that instinct to a great extent outwards. ... The instinct is then called the destructive instinct, the instinct for mastery, or the will to power.
It is this "instinct for mastery" that Derrida focuses on in "To Speculate--On Freud" casting it as Life Drive. The gist is that the death drive and the life drive are two sides of the same coin. For instance, the drive to master one's environment can transform into aggressive warfare. (It was the aftermath of WWI that caused Freud to think of the death drive.) On another scale, problem-solving tenacity can exhibit pathologically as repetition compulsion, (same ref.).
