I recommend that you have several (ie 10-12) little cups nearby with a pen and some small scraps of paper to write on. As you remove screws, step by step, place that step's screws into one cup and label it "Step #X". That way, when you're putting everything back together, you won't have to guess as to which screws were for which step. I did this, on a recommendation of a friend who did this very same repair, and it made the reassembly even easier.
