The hardest part of learning motion graphics and compositing is the art not the software. While there are new and improved tools in recent versions, everything you will be learning applies to CC 2014. If you go through the entire book and you study and learn you'll be ahead of many pros that work in productions houses across this country because Chris and Trish are just about the best at teaching this kind of stuff.
Get the latest issues of Trish and Chris's books but, as Rick says, there are few humans who know the art and craft of animation nd motion graphics design as deeply as these two. And they are great teachers.
I agree with bogiesan. Get the most recent version of Chris and Trish's book. It's worth it.
FWIW, they're the ones who taught me After Effects.
