Hey, and welcome to the forum.
First of all, you cannot fit a BOV to the Polo TDI, or almost any diesel for that matter. The wheels on the Golf in the first picture will not fit your Polo either unfortunately (well, not legally anyway). This is because the stud pattern (PCD) on those wheels is 5x112, and the Polo is 5x100. You could get wheel hub adaptors, but these are illegal in all states (you can risk a defect, or your insurance if you do run them). You might be able to get replica's in the right PCD for your car.
As for the colour coding of the rub strips on the doors and bumpers. They are colour coded from factory, and as far as I know, will have to be painted. I'm sure a Perth local could point you in the right direction for a good panel beater/painter.
