Ion-gated channels as the passage of +/- ions are required to cross the nerve membrane causing the nerve to fire and causing movement.

It's either acetycholine or serotonin. I would stick with acetycholine.

Actually, the acetylcholine receptor is a ligand based ion channel that increases the permeability to the sodium ion. The later increase in potassium conductivity is caused by the voltage-gated potassium ion channel, not the acetylcholine.

there is an end plate potential (local graded depolarisation) which spreads in both directions. It is above threshold so voltage-gated sodium channels in the muscle cells open and allow the influx of sodium, which then causes...

All of the above. Acetylcholine esterase breaks it down at the synapse, it diffuses away, and some of it is recycled and taken back up by presynaptic cell.
