I am not aware of any way you can display the tracks onto your EAsy 1 or 2 INAV. If you find a way of doing it please let me know because it would be a useful feature.
All the info you want will be found in your MNPS/RVSM manuals that come with your Ops Spec or Approvals.
If you are flying Westbound into NY area be aware that you will be required to descend quite a bit earlier than you would normally. Take a bit extra for this.
