Answer: To answer the first question, it's some sort of tubing and fluid from inside of Robocop... so something like oil or something along those lines. Something that Robocop's robotic body uses to function. As for the second question, I do not believe it's ever mentioned specifically, but online searches say it's over 300 new directives. (Though we never see all of them).
