Welcome man,
heres a link to a write up on changing out interior lights

I think its mostly just plug and play, just need to make sure you get the correct bulb size.
I'm not sure if it varies between the years of our cars or not. Maybe someone can jump in on that answer.
As for the dash itself. thats another story. theres write up that someone did with their 08' and didnt have to change our the LEDs.
Basicaly scraped of the red/orange tinting around the rings on the speedometer. Also another member here used to do the LED swap,
but he no longer does it. I forget who it was though.
