If you are starting out from absolute scratch then, yes I would recommend this book. It gives a good general over view of everything to do with playing bass, including some basic theory.
Another book which is very good IMO is : http://www.amazon.com/Leonard-Bass-M.../dp/0793563836
The three volumes together (as in the link) in one edition, is money well spent IMO. Each volume has it's own CD.
