Rooting by itself does nothing (well, initially unlocking wipes your system) except allow you to modify the system, boot, recovery and data partitions.

I recommend reading as many threads in this forum as you can stomach. There is a LOT of very good information that will help you in the long run.
PS - You can turn off location services in Settings > Location if that's all you want to do. Just uncheck all 3 location services. Done !
