With the book you can quickly get the basics, but it sure is bit out dated. 
You can always find the latest documentation at 
http://www.erlang.org/doc.html and especially from the link "Erlang/OTP 
R10B documentation" (which at this time points to 
http://erlang.se/doc/doc-5.4.8/doc/). There you can find "Erlang Reference 
Manual" and "Programming Examples" which are very usefull when in doubt.

List comprehensions (||) are explained in
http://erlang.se/doc/doc-5.4.8/doc/reference_manual/expressions.html#6.22 
and 
http://erlang.se/doc/doc-5.4.8/doc/programming_examples/list_comprehensions.html#3

The list concatenation (++) is explained in 
http://erlang.se/doc/doc-5.4.8/doc/reference_manual/expressions.html#6.15

Hopefully these will help you.
