To answer your inquiry a year or so late

Dexter had it in his possession but does not anymore due to his sending it back to Vince so as to get rid of Louis. It can be assumed that Vince snuck it back into the ITK evidence box

Dexter did see it several times

The palm chart lines were supposed to be a threat to Dexter from Louis. The gist of it being that he diagrammed the "Life Lines" because "Dexter's time was running out."

Louis was just trying to scare Dexter, but didn't realize that a man with 130+ kills under his belt doesn't scare easily
