1 - absolutely not
2 - air, oil filter, and oil company
3 - copper is just as efficient; iridiums just last longer and cost more
4 - overkill for your budget-grade mass produced car; just use Shell HX-7 5w-30, Total Quartz 9000 5w-30, or Caltex Havoline 10w-30, whichever is cheaper.
5 - ABS is supposed to make noise; it will slip in situations where the terrain changes it's consistency mid-brake. This mainly happens because it's a budget grade sedan.
6 - the FCD (Fuel Consumption Display) is slighly out of calibration; in your case it is underreporting the fuel consumption. It's nothing much to worry about; if you are borderline OCD, you can get it adjusted from an authorised Honda workshop.
