A light box/tent provides extremely flat lighting; that's the opposite of what you want for showing scratches/textures. I don't know of anyone who does high level product photography that uses one...

But to start, use just one light off to the side at more of an angle to show the textures (up to 90*). And place it right against the fabric in order to make it smaller/harder. That's about the best you will do with the tent setup for showing texture... then combine it with these setups/results (i.e. add other lights).

For highly reflective subjects I find it is easier to think of creating the environment the object will reflect rather than lighting per se. I.e. if you want an area lighter, place something lighter colored there (lighting); and if you want it darker, place something darker there (negative lighting).

As far as the frontal image and lens reflection... you did well creating the white mask. The next thing to do is the make the reflection much smaller by using a longer lens from much farther away. Then the reflection may be small enough to be easily edited out, or you may have to intentionally place the reflection slightly off to opposite sides in two image to combine in post.
