The LED headlights with harness new is around USD 1300 plus shipping of $70. you need to splice the wiring and connect on projector wiring.
The Cluster thing is not easy. It's too much complicated and will be too costly. Also once you import you never know all features on the display will work. Steering wheel controls as you see on USDM are compatible with Apple Car Play/ Android Auto unit.
At this point.. If any upgrade I would suggest after buying would be just headlights. To be honest I would not even recommend it till a year or so after ownership in case you have unfortunate warranty claim and dealer try to decline.
As far as cluster.. remember once dashboard opens.. it is never like before.. squeek, noise will start no matter how better you refit opened dashboard.
