Matches And Differences Between Two Lists

I am trying to compare matches and differences in two lists in order to pull statistics from them.

I have a production schedule I make at the start of the week (list 1) and compare that to what I actually ran at the end of the week (list 2). I would like to produce the following from these two lists;

- a list (list 3) that shows all the orders I didn't run in my original schedule
- a way of summing the number of matches (of work order #s) in the two lists (list 1 and list 2)
- and way of extracting the corresponding machine hours I did / did not run from the two lists

I have provided text boxes on the attached excel file to better explain my problem.
