After some research, let me reply my own questions regarding methods: @ http://tesseract-ocr.googlecode.com/svn/trunk/doc/tesseracticdar2007.pdf, general flow chart is explained thoroughly, with method names. However, I don't seem to be able to reach referenced documents, which is a shame at my end.
However, I'm still concerned on using Tesseract-OCR with my preferred settings (first part of the initial post).
