best method for creating chrome is to plug the reflect node into the ALTERNATE DIFFUSE slot, and set the standard diffuse to black and the diffuse value to 0. this will give you a very clear and crisp reflection. to do silver, set the alternate diffuse color to a meduim grey (with the reflect node still plugged in, and set the standard diffuse amount to around the .4 mark. set the standard diffuse color to a blue-grey combo. or a goldish color (for gold Obviously)
