In response to your desire to upgrade you headlights, I would agree with you that the lens used on these years of V8 cars in USA is inferior to the European models, as is true of many european cars brought into USA before recently, and would agree with your desire to upgrade the lenses before the bulb, especially since I think the replacement lights are the 1 bulb system with a built in fog lamp instead of the two lamp system you currently have. the light upgrade is available here in the US from a couple of places but it will run you around US$1200+ for the pair. the nice thing is that your car will look much like many of these found in the gallery on this website and the marker light is built in to the lamp system. let me know and i put you in touch with someone who you could purchase the lights from.
