Booked J on JAL from KIX-HND-CDG through American Airlines.

Couple questions:

1. My KIX flight departs at 6:45am. Since I’m connecting to an international business class flight, will I get any kind of expedited security at KIX? I’m currently booked at the Hyatt Caption Osaka, but wondering if it’s easier to just cancel my last night and stay at Hotel Nikko Kansai to simplify the early morning.
   
2. Will I need to collect my bags and re-check at Haneda, or will they be checked through to CDG? Do I have to re-clear security or just change terminals at HND?
   

Thanks for any tips!
