Out of your list, only the air filter need be replaced as a "consumable" item. Generally every 30K is when it's a good idea to replace the filter. We check customer's filters at every oil change in my workshop and if the filter is excessively dirty, we recommend a new one immediately. I also check the air filters on my own cars every 3,000 miles or every oil change. I will usually remove the filter element and gently tap it against the floor to remove any big particles which may be trapped in the filter medium. My own cars receive new air filters every 30K regardless of their condition.
