Not sure if Ford uses LED's for the cluster lighting or not. As far as I know, the lighting didn't change between 2012 and 2013 (for the cluster, the interior lights might have gone from LED to incandescent), but the speedometer only has numbers every 20 mph rather than every 10 mph.
Disc brakes are nice, but not a huge deal - there's another long thread on it. They weren't standard on 2012 SE's either, but they were part of a $700 option rather than a $2400 option.
For the polished trim - I would recommend Plasti-Dip, as at least it is removable if you don't like it.
