I was in the same boat. The overall call quality is better than the gen 1. The calls/sounds are more crisp and better base. People who i call cannot tell I am wearing Bluetooth headphones. And the added speaker on the case is nice. It emits a sound when placing on wireless charge pad and you can now locate the case when it falls deep in your sofa. You can also now charge the gen 2 with the same charging puck for your apple watch.

Nope! I traded in my AirPod pro 1st gen with just the case and earbuds. I placed a pick up order for the AirPod pro 2nd gen usbc, went to pick it up and traded in my 1st gen with a breeze. Didn’t need the charging cable or any of the accessories
