You mean Han using Luke's saber to cut open the tauntaun? We've also seen a whole bunch of non Force sensitive Mandalorians wield the darksaber as well as that jumping alien who stole Ahsoka's saber in the Clone Wars. So no, it's not a new concept. I guess we'll have to wait and see.
Yeah there's nothing special about using a lightsaber as a muggle.
If they're bouncing blaster bolts I asune they're force sensitive.
