Can someone tell me the difference between Spin() and SpinOnce()? And what exactly they are doing, is it like a while loop to process some ROS stuff?

This is covered in the ROS Overview in the Callbacks and Spinning section.

Both calls trigger the processing of callbacks. Chapter 3 of the new A gentle Introduction to ROS book does a good job at explaining this.
