What is the sequence of ATC frequencies for final approach at JFK?
"Final 132.400" is final vectors (sometimes called 'final sector'), an intermediate stage between approach and tower. Whichever route an aircraft arrives, the relevant approach controller will hand it over to 'Final' for final vectoring onto the relevant final approach. Once the aircraft is established on that final approach (with proper spacing), it is handed over to tower.  

I would recommend listening to Final first, whilst simultaneously watching a certain well-known flight radar website. It may take a few minutes to get 'in sync' with what's going on there, but you should soon get the gist of it. Then listen-in on the approach sector(s).
