If I'm understanding your question correctly, yes you could take it to the dealership to have those items replaced. Or, you could do them yourself and save a lot of money. None of those services are difficult and are extremely commonly done by the owners rather than being taken to the dealership and overcharged.
And before it's asked, you do not need the dealer to do your regular service to maintain your warranty, just keep documentation of all maintenance work performed (dates, mileage, receipts, etc) whether you do the work yourself or take it to a private mechanic.
