Pretty much as Dibs has said, just make sure you put everything back in in the same order you removed them. You should keep all the steel plates in order and note where the indented tab is on each steel plate etc also.
If you have a digicam might be worth snapping as each plate is removed, might be over kill but if you're unsure it's better safe than sorry
