I've got an inflateable aboveground pool we set up for my kids in the summer. Does NEC *really* require an equipotential grid be laid down before setting it up, and a ground electrode draped over the side? I mean, it seems absurd, but it sure looks like it; they even go out of their way to say this chapter applies to storeable pools as well as permanant.
To answer your question; pretty sure the pool guy will install the ladder, and possibly the bond as it SHOULD come designed for code-compliant bonding. If he doesn't supply the bond, you would have to. The customer will pay for it all.
No "storable" pools are not covered by chapter II of the NEC. See Chapter III. The main issue is that you are using all "storable pool" equipment. It should be so marked. This is all double insulated and the pump comes with a long cord (25')
Ladder cups usually get installed by the guy shooting the concrete and they usually do all of the concrete encased bonding around here. This may be inspected by the structural inspector but there is an "electrical" box to be signed off on the permit so it really should be an electrical inspector. These days most inspectors are multi-rated. Departments protect licenses when times are tough and the more licenses you have, the better chance you have to keep your job. The way it worked on my pool was I saw an electrical and a structural inspector before the pool was shot and the electrical inspector did the final. (verifying the fence/cage, alarms etc along with the electrical finals)
