yup same wiring minus one bulb, not sure about drilling for the center piece, yep you do have to drill for the number plate lights another way around it could be to remove the studs on the lights and double sided tape or sikaflex them on i guess, for wiring you should be able to get a park light from your rear tail lights somewhere or slice into your existing bumper lights.
levin86 here has redlines, in his build thread you'll find his install.
as for rubbing A4 paper to polish them up i've never heard of that, give it a go? better off use some super fine wet sand paper like 3000 grit and then respray them with clear coat, will come up new
