You are on the right track, and it looks like one of the problems you are coming up against is that the styles are not quite large enough to fill the letters to give you the edges and lights/shadows you are looking for.
I played with a letter set in Linotext--not the same font, but it had some nice curves so I could give you some options.
Here is an example of a metallic feel using the Bevel and Emboss settings in the Styles Dialog. The thing you can't see is the contour which gives it the metallic shine and reflective edge. See the next example to see what the letter looks like without contour, and then look at the third option to see the contour I used to get this effect.
This example below is what the Bevel and Emboss Style looks like without Contour applied. See the next example to see what contour I used to create the metallic effect above.
(if you don't like the flat areas in the type increase the size slider in Bevel and Emboss).
One other think I thought about is that if your type is too large for the Bevel and Emboss to be really effective, you might try cutting your letters in to halves and applying the effect to both halves of the letter.
I hope this helps your creative process...Let me know how it works out!
You are very welcome. It is looking good!
