I am in the process of looking for new headlights and fog lights. I have found some, listed below, can you tell me if these are good?

1997-2003 PONTIAC GRAND PRIX HALO PROJECTOR HEADLIGHT | eBay

Navigator NV-602W Cyber White Driving Light Kit Feature | eBay

Will these fogs fit like the factory ones?

I want to add HID to the new headlights, do I need special ones for these type or are they just like the ones I have on my stockers? I will get new ones because I want to get both the hi/lo ones.
