The coolant flush is definitely going to happen. It needs it. I plan on doing all the regular maintenance as well, including changing the supercharger oil and a trans flush. I'm almost positive neither of those have been done.
If you even think the radiator is bad clogged or etc, swap it, theyre cheap from ebay ~$60. I ruined 1 engine by not doing it. If you have the time replace the valve cover gasket the factory ones can leak and cause fires.
