I really dont know what the problem you're describing is, as you can see theres nothing wrong with the textures.(print screen + 3 renders)

The only thing i can think of is that you're trying to apply the same texture on both arms when each arm has a seperate texture file - named rightarm.jpg and leftarm.jpg .

If its not this, post some pics on you're blog so i can see the issue, because i can assue you its not the textures.
