Nadine, for the metal elements, you might need a combination of the Embossing and the Chrome effect. Considering that a real 3D effect plays with perspective, it might be hard. I tried to play with something similar when making a coin, like you would see a 3D head on it, but it is not as simple as black and white.
As for transparency, it if often a matter of playing with the Opacity. This might actually be a cool question for the Q&A so I can demonstrate it.
