Nice car, the blue looks great!
Where did you go for the ID check? Hopefully nothing too major to fix by the looks of it, should be able to do the lights. When I had to do my tint for inspection I went to a tint place and they removed the old one (which let me go through the inspection) and then put new - legal stuff on afterwards, all for the same price, i.e. let me do it over 2 visits to them. I am sure many places would do the same.
As for the gauge/pillar I guess a Japanese wrecker/workshop place, depending on where you are in Adelaide there are different shops.
