Re: importing mtl file
No wavefront expert, but in the few lines of .obj file you quote, there is no usemtl (material name) which I believe is the link between the group in the .obj file and corresponding material in the .mtl file.

https://en.wikipedia.org/wiki/Wavefront_.obj_file#Referencing_materials

Could that be the reason?
