If you don’t know much about in-game animation, it might be a good idea to watch a few existing tutorials (like the ones provided by Epic) before you consider purchasing the system. My system is essentially a more advanced version of the default third person template, so you might want to start there to get comfortable with the in-game animation process.
I probably wont be able to make a tutorial at the moment, but the system comes with extensive documentation that explains what everything does. This can help you understand the system so you can expand upon it. The system is also built to be very flexible so expanding on it isn’t hard it you understand the logic flow :).
What kind of IK are you planning on implementing? IK shouldn’t be a problem with or without root motion.
