Reply to Tips ForA Beginner With A Modest Modular Set Up

Hi all,
I just got some DJ Gear for my son for Xmas and wanted to get some feedback to get him off on the right foot. He's set up with the the Kontrol S2 and the F1. I have two questions.
1. Should he start with just the S2 and get dialed in on that before using the F1 or should he just dive right in on both pieces of gear?

2. Should he start with a custom map (I've downloaded BB's S2 mapping) or stick with the the default S2 settings for now?

About my son....
He's 15 and loves making beats. He's actually gotten pretty decent at getting around in FL Studio and is dabbling around a bit in Ableton as well. He's A.D.D. so his patience can run short sometimes. He is LOVING his new rig and I want his learning curve to be as sweet as possible. He's spending a lot of time with it but is really hard headed when it comes to reading manuals or watching video tutorials. I'm doing that myself and helping him but I'm just as new to dj'ing as he is. I realize that these questions are subjective and that there is no "one" way to go. I'm just trying to get a little feedback. So please sound off! your comments and opions are welcome and appreciated.
Thanks in advance.
