The book covers version 2.0. Many of the examples were updated to reflect 2.0 after originally being written for 1.0. There are even a few mentions of 2.1 features, but most of the book content was completed before 2.1 was stabilized.
I am new to Spring integration and have got some exposure to BizTalk but know Java and limited Java experience. Would learning Spring and specifically integration be a steep learning curve in your view?

I think many of the high-level concepts would carry over from your BizTalk experience. I would recommend spending a bit of time with the Enterprise Integration Patterns website (or better yet, the book itself): http://www.eaipatterns.com
You can explore the "Integration Patterns" on the right hand column there.
One of the goals of the framework is to allow you to keep your Java code as simple as possible - and most importantly, focused on business logic rather than integration concerns which are instead handled by the framework.
