Napa and prestone make a radiator flush kit,which back flushes the cooling system. Works very well. IMHO if your thermostat is working properly now then there is no real need to replace it.
Fleet Charge is a good coolant but really for about the same money you could get an ELC and just run that and be done with your coolant for 6-8 years. Delo, Rotella, Cat, Zerex..etc etc all make Cat EC-1 compliant coolants so that might be your best bet. Any heavy truck shop will have the stuff.
