Definately go to a Rock shop info clinic - I went to one about 2 years ago and learnt heaps!! - then you just pick up the rest as you go along. Its more about understanding how everything ties together within the environment...which they normally cover really well at The Rockshop clinics..
Yeah, that environment window takes a little getting used to - expands the versatility of Logic though. Looking forward to asking a few questions at the information clinic!
