Connecting Garmin Edge 1000

Hi,
1st time poster and newish Zwifter so please be gentle!

I have a Tacx Neo 2 (Love it!), run Zwift on a laptop and have a garmin edge 1000 head unit as this seems to be the only way to see some cycling dynamics info.

I’m getting a little confused on what sensors I should be connecting to the garmin in my ‘Indoor’ profile:
Should I just have the Tacx Neo connected as a an indoor trainer, or do I need to also have it connected as a cadence sensor, speed sensor etc?

I also could do with help on whether best to pair things via bluetooth or Ant+ between the Neo & Zwift… i’m not getting road feel in Zwift despite it being turned on, but not sure if it’s because i’m connected the wrong way?

Any help appreciated.
Thanks
