- have a massage and a shower after (call before to book your massage slot)
- have a lunch (more or less late depending on when you had the breakfast) in the lounge
- have dinner in-flight to SIN
does that sound a good plan ?

This sounds like the best plan indeed.
But personally I would not look forward to spend 9 hours in the P lounge.
From the time you reach JFK (say two hours before AF9 departure) to the moment you leave SIN, you will spend over 30 hours in airports/planes.
A lounge is a lounge and 8 hours there will be extremely boring after an overnight flight. I would rather get some fresh air and maybe get a stroll in Paris.
