These are 2 general improved/better/best practice techniques/processes for disassembly and assembly.

Use tape to keep cables out of the way AND on top of boards and other components as the boards are put back into place. This (1) makes it easier to put boards back in place and (2) prevents not seeing cables and having them get hidden under the re-inserted components.
Print out the repair guide and tape the screws etc onto the picture in the positions they go. This (1) prevent loss or misplacement and (2) prevents confusion when determining which screw goes where when re-assembling.

Print out the repair guide and tape the screws on the picture of where they go.
Have a desk tape dispenser (so you can use one hand to get a piece)
As you progress through the steps/sheets you can move and stack the sheets to the side.
