Answer 1

For word documents, you can try antiword, at least on linux. It's a command line utility that takes a word document as an argument, and spits out the text from that document (as best as it can figure) to Standard Output. Maybe you can specify an ouput file too. I can't remember the details of how it works. I haven't used it in a while. Not sure if it can handle OO documents.
