Theres many other threads that go over this topic and have complete part lists including the brackets
Heres the ones Im using as I'm in the process of doing the facelift as well. Im going to Autobiography route. All the parts as far as bracket wise are mostly the same.
Heres the link that I used for my parts list. This link is to a members thread that did the Supercharged Facelift. But again, if your only using it for the brackets, they should be all the same. PowerfulUK has all the brackets you would need, and Ebay is a good place to get them too.
Hope that helps.
Yes, front headlights and rear lights should be plug and play.
Now, the taillights you will have to wire in a resistor or purchase a resistor kit for them, as the inside turn indicator will blink twice as fast, as if the light is going out. Thats because the LEDS use less power than the regular one, so it causes the car to think the light is out.
If you can live with the fast blinker, than it doesn't need anything. They will still work without the resistor.
