Edit Step 4 ¶
Insert an iPod opening tool between the outer case and the display retainer.
Use the tool to slide the display assembly out of the case slightly.
Do not rotate the display retainer about the top edge of the display, as it is attached to a thin steel bracket that is easily broken.
Do not forcefully remove the display retainer, as the hold switch cable is liable to snap.

Edit Step 16 ¶
Use the flat end of a spudger to separate the battery from the adhesive securing it to the outer case.
The lithium polymer battery used in the Nano is very flexible. Try not to deform it excessively while separating it from the outer case.
Use the flat end of a spudger to push the logic board assembly and battery slightly out of the bottom of the Nano. Stop once it pops out a little bit.
