The steering wheel chrome can be dipped/painted/wrapped pretty easily, you need to remove the airbag and then the trim comes off the wheel.
The center vents along side the radio the chrome is part of vent. Remove the center radio trim trim panel in order to remove vents to work on them.
The outer air vent trim is part of the dashboard panel they are in. Not the vent itself. They are trickiest to get apart and back together without breaking stuff and making it look right when done.
The shifter trim is part of the boot. You need to remove the shift knob and then the boot/display assembly. The chrome isn't serviceable, but it should be relatively easy to get off.
