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.

Better still is to print out these instructions. Then as you remove screws, scotch tape them to the instruction sheet right on the place where it says to remove them. The tape keeps them from getting lost and the order can't be screwed up.

These were such great directions!! It was no harder than baking a cake. I didn't have a spudger, but a thin plastic chopstick worked fine. I took lavatop's tip to print out directions and tape the screws in order. It was great advice. Thanks IFixit!
