That's pretty cool mate - and a good pick with the AKAI (I've got the same one myself). My one recommendation with DAWS is don't worry about all the fine control - get it running in a way that works for you and then you can build on that knowledge (I'm using Reaper myself and I still find myself going back to tutorials about how to do basic shit). One other thing I would say is learn how to use the MIDI editor (piano roll) and your life will be so much easier.
If you're looking for a good free package of instruments (the ones that come with the MPK are fine but a bit generic) then check out
LABS by Spitfire Audio. They're great quality, 100% free and super versatile.
