1. get temporary permit to drive solely for the purpose of getting to the compliance place.
2. Different RAWS are "qualified" to do specific cars, check with them first.
3. ~$1000-5000, sevs.. aka step by step costs
4. 1yr, bad luck. best case: few weeks shipping, then few days compliance then on the road.
5. not sure sorry, i'm in perth.
