If so, how? do i need to earth the dimmer switch to the earth terminal in the wall box as well as the existing earth in the first picture?

You do not need to earth the back box, you do need to earth the switch plate. You can just move the earth wire and reconnect it to the switch plate.
or
take a short piece of earth wire and connect from switchpalte earth to back box earth.

PS You should mark the black wire with a piece of red sleeving or tape to show that its a live wire and not a neutral.

EDIT. You may need a deeper box. You'll ahve real problems to get the dimmer and the wires in that 16mm deep box. Dont think you'll do it by screwing down tight - you'll crush the cables and cause a short.
Also you will need to remove the top and bottom screw lugs, they will get in the way.

As one who is training to be an electrician, I under went a colour blindness test, luckily the result was negative.

That room though, it looks very un-green to me

Read the instructions for your GET flat-plate dimmer. You may find you need a 35mm box.

Yeah, nice and pink.

Will check out the box, if a deeper box is needed i presume that means hacking away at the wall.

Oh the joys!!!
