Section 1b - Pre-root follows:

You'll need to read these threads before proceeding. They'll ensure you have adb and fastboot set up properly on your Windows PC. The first thread should install everything you need (adb., fastboot and drivers) to be able to connect to your Windows PC and subsequently gain root access. After following the first thread, check if it works correctly by booting into the bootloader, connecting via USB, then entering "fastboot devices" into a command prompt window. If your device doesn't show up, then try manually installing the driver in the second thread. If you continue to have driver issues then diagnose your issue with the information in the third thread.
