Dude I followed every single step described on each guide I found. I downloaded MCC, Analog lab 4 and Ableton Live lite (still haven't used this one because I already need to learn using the Keylab :p)
Well, you should know that Ableton Live is like an elephant. Unless you apply yourself by taking several hours per day, it'll take forever to master. It's one huge software to learn. I've been at it for about 2 years and only scratched the surface. I bought the Intro version for 100.00 or so and then there's the stuff in the more advanced versions.
It's a complex software but it is surely capable. Sometimes I use their own instruments and other times I use Analog Lab or Modular V plug ins.
As for Analog Lab 4, I spend months going through each preset and placing them in my own banks. I've created banks to represent different types of instruments like (PERCUSSION, BRASS, PIANO, ORGAN, SYNTH, FLUTE, STRINGS(Plucked), STRINGS(Bowed), DRUM kits, KICK drum, PADS, FX, SEQUENCER) and so on since I need to look for a specific instruments or background sounds.
It'll surely be time consuming but definitely well worth it.
