1) avoid nockoffs of seat posts, stems and handlebars. Well known 2) A worn front chain ring won't negatively impact a rider. 3) it is a bicycle, not a helicopter. 4) Fear mongering is unnecessary 5) A torque wrench needs to be consistent. so long as it is within 10% you are fine 6) sounds like a bike shop owner trying to drum up business.
