No disrespect intended Frank, but armed with the apparent level of expertise needing to ask the questions you are asking, you would be doing yourself a huge favour and avoiding a lot of 'pain' in future by buying yourself copies of this and this and reading at least the first [u]before[/u] you start. A relative pittance compared to the time and effort involved in the refurb you're intending. No need of the former, I do have and have read the latter. Not the bible, but pragmatically comprehensive & unquestionably, worth the spend. Recommended.
