Raymarine Package with new Azimut 50 Fly

Hi,

I am buying a 2018 Azimut Fly and it comes with a Raymarine package:

4 a125-two on fly, two at inside helm
2 VHF 260- one on fly, one at inside helm
ACU 300
EV-1
2 p70r
2 i70
DST800
VCM 100
HS-5
2 RMK-9
Open array HD 4kw 48" color

I want to add AIS transmit and receive, and the FLIR M100.

One how is the factory set up I described? Some people say it's old and better/newer is available.

What unit do I need for the AIS?

Can I add the M100 and how is it?

What charts should I use? I am coming out of a GARMIN 7616 set up? I assume Navionics is best?

Thanks
