What I do to make the chiny parts go away is turn the Reflection color to black and turn the highlight size all the way down to zero. Set the trans min, max, and fall off to the Maximum. As a recommendation for a shiny metalic color, here is what I do to acheive a silver look maybe you can change the colors for gold: I set the Ambient color to a dark grey, highlight to white, and object color to a light grey. See if that helps any. If not, try fixing the transmap to apply to the catsuit like Balaan suggested
