If you are after a book that goes C++ in depth, the book you mentioned is a great start. Though if you are a beginner it may not be the easiest thing to work through.
I would also recommend the C++ tutorials found here: http://www.cplusplus.com/doc/tutorial/
They will teach you all the basics of C++, and will help to supplement the stuff you are reading in “C++ Programming Language 4th Edition”.
As the for the having to learn C++ and Java at the same time, I personally do not think it is a good idea (though others may disagree). Learning C++ can be a challenging process on its own, let alone throwing another language into the mix.
