In Unity, click on your fbx, then click the rig tab on the right side of your screen in the Inspector. Click configure, and in the mapping tab on the right, make sure that Upper Leg is set to upper_legL and upper_LegR for both your left and right legs. Also make sure that Hips is set to your hip bone. As for facial expressions, not sure what specific problem you're having but an easy mistake to make is not setting the weight of a layer to 1 in the animation controller. Otherwise it won't work.
