Yes. This, defiitely this.
The mature libraries for Python are what is probably going to block Julia from really taking off IMO. It should also be noted that the benchmarks posted on Julia's homepage don't incorporate these libraries which are, when compiled, usually faster than what most people can reasonably do in C.
As for books, Wes McKinney's book (he's the guy who wrote Pandas) is a great place to start.

4 stars is probably lower than it should be. It's an intro book focused on the tools. If you understand it's that and only that, then it's great.
