Latch metal and bump mapping

For the latch metal on the box I used the same texture from Mayang that I used for my pocket watch, but I edited it to give it an orange tinge. However, the shine in the top left of texture is too intense and doesn't match with the light source. Using the cloning tool on Photoshop I quickly fixed this:

 As I was going to bump map this model on all the polygons to really bring out the leather texture, I wanted to add lines to the latch to make the leather different components actually seem separate:
