As far as additional resources for TBP... I am not sure you really need any. The book Extreme Toyota mentions TBP and has a few case studies and A3-type stories that follow this process, but not in great detail on the thinking and tools used. Managing to Learn by John Shook is also a good place to get a handle on the Toyota way of working. Read some classic Deming on PDCA and you can't go wrong. The content of TBP is nothing proprietary so if people need more details on the 8 steps let me know and I'll see if we can't put together a PDF or something to download.
