Any info on A) Changing Belts (how to) ?
B) Changing Hoses (how many mi/time) ?
C) Thermostat Change?

 

Unless you are having an identifiable problem with any of those, It's way too early to be thinking about changing them. Wait another 3-4 years, periodically checking the belts and hoses for signs of deterioration. All this my opinion, of course.
