Ummm....stay away from so called "projector" headlight conversions such as the ones you linked to. They are merely standard housings with a glass "mirror" attached with screws. It's by no means a true projector setup. It's only for that projector look. Hid's need a proper housing to operate in or else glare is hugely increased. There is no current aftermarket true projector retrofit housings to replace your headlights. The only way to do it is fabricate your own. If that's not possible then the next acceptable housings is Hella E-Codes. E-Codes stand for European Code. They produce a sharper beam cutoff......less glare and more concentrated beam pattern.
Check this thread out....lots of good information

As far as the foglights....keep in mind that a halogen....no matter what kelvin they rate it at....will not come close to the brightness and color of a true HID bulb. So when you go HID's for the lows and put a halogen in your fogs, it'll look mismatched.
