Vlada I'm spending my time on the Groove3 NI tutorials trying to go through every feature so I've only used it for a few synth parts right now. There is just tons of stuff you would never see that Groove3 points out, as I spent so much money on it I'm keen to optimize the value of my investment.
I would really suggest you've got to make time to learn. I totally sympathise though sounds like you have a tough gig already. Even 3 hours a week would be time well spent. These forums are great for real world advice, experience, troubleshooting, and for tips. But won't help you much in improving your mixing skills, videos are great for this... If only you could see the bags under my eyes right now...
Oh and to add, I used to work in recording studios every day in the early 90's. I got a lot of experience but I swear these videos give me more knowledge in a few weeks then I got over several months looking at a manual, reading books and asking (way before the internet was useful for this).
BTW Right now going through the Absynth 5 tutorials, horrible looking UI but it's extremely powerful away from the presets.
