Maybe take a look at my build log (the link is below) Different brand truck and I am deleting the armrest completely but it sounds like you have similar goals for your build.
As far as what esle you should put in the console, I would suggest it will make a good home for the PC as well.
You should post pics as you go along. Members would really like to see your project as it progresses.
BTW, welcome to MP3car!
