Removing Interior Trim

Anyone got any clue on how to remove the interior trim around the around the radio and air vents. and any idea on how to remove the steering wheel to take of the silver piece on the lower half (all are being wrapped but have no clue on removing them).

cant help with the bits you mention. However i have taken off the centre console and the orange bits just pull upwards and off and the rest unscrews or pops off.
