I didn't unroot before I flashed this. However, you will lose root. The new boot loader has the Knox flag, which means if you root this firmware, the Knox flag will likely be set and that may void your warranty. I'm just using mine without root at the moment.
Steps I did was to do a factory reset in stock recovery, then used Odin 3.0.9 to flash the new firmware. Google search for a guide to using Odin. As I did a factory reset, had to install all my apps, etc. again. So, back up anything you want to keep before you start.
