Correct. Add that code snippet to you theme functions.php. Yes, this will and need to run on every page load. The core WordPress register_taxonomy functions also run on every page load. The code I provided is just changing the label AFTER the core register_taxonomy functions are run.

See above comment. This is the way the WordPress taxonomy system is setup. Runs on every page load.

No. You are not updating any WordPress core file. This code I provided goes into your theme functions.php file.
