There’s a bunch of things wrong, the armature and mesh are rotated, the mirroring is on the wrong side (you should model the other side instead, but I guess it doesn’t matter since you need to apply it anyway). Remove doubles to merge the center vertices together. There’s scaling done on the mesh in object mode so apply transforms to fix that, enable Deform for the bones in to make sure they can actually deform to mesh. You should probably join the meshes too, and fix the bone parenting. Then parent the mesh to the armature with automatic weights and it should work.
