Tethering and root access are unconnected: my phone can tether and is unrooted. Maybe if you get your phone from a US carrier these things are related, in which case, buy elsewhere?
There really aren't any reasons to try and root an Android phone. If you want to replace the OS with some custom open source build, just use a phone with an unlocked bootloader and go wild. But you can already access so many features and customise so many things without root it hardly seems worth it.
