There shouldn't be a "need" to update any software, it's not normal maintenance unless you have an issue related to a fix provided by the release. Also at 22k, you seem premature to do plugs and rear diff fluids. Plugs and diff oil don't go "bad" like milk in a warm fridge, or like brake fluid that absorbs water reducing its boiling temp.
