you might be able to with other makes but as far as I know it is not possible for the tacoma. Just from reading your mod list I would not worry too much about running too lean, although it is always nice to know where you are at.

You shouldn't have any reason to worry about your AFR, and the scangauge wont be able to read it.

URD most likely because of its true cold air intake qualities. i didn't get one because i didn't want to snake the tubing through to the front and its not legal in California anyway so it takes longer with the setup to revert back to stock when i need to.
