Yeah mate they are slightly different, the honeycombe grills look a little nicer than the standard Diamond type grills.
Give Volkswagen a try for the lower grills, they are quite hard to get hold of second hand so I would just try to get a new set from VW.
I know what you mean about the headlight protectors and I felt the same at first but when I got a set & fitted them I thought they looked quality.
They only cost around £7-8 for a set so its not much of gamble if you dont like them, they literally take 2 minutes to fit as well.
LED Sidelights and a HID kit make a hell of a difference, its worth upgrading your Full beams too.
You will need a H7 HID Kit (6000K looks great), LED Sidelights and H1 full beams (Osram Nightbreakers)
Yeah you can get all of the above from eBay mate
Here's a link to my old build thread

Sold up because I wanted something a little quicker , loved the Polo though and its gone to a great home so I cant complain.
I had to change the gearbox in March and that made me look at some different cars, decided on the Honda Civic Type R in the end.
