Reply to Learning Traktor 2

Hello guys

I'm very new with the software. What's the best way the learn it? How good is "Traktor 2 Bible"? I'm trying to learn it with my S4 controller but I get stuck all the time

Edit: And another question I was trying to record some tunes but the files are always very huge. How do you guys record your mixes etc. How can I compress the file without any quality loss

Sorry for my English
