I know how to look in MyTmobile and see how much overall data I've used, but how do I know how much tethering I've used???

Are you able to see this usage using the T-Mobile My Account app? If you check the section of the page that says How-to guides: all platforms it has steps on how to check the usage. It's really neat because it gives a clear breakdown that separates the usage for you.
