Thanks to the excellent help of the forum members here, especially Laurie, I am happy to say I think I know what I want and where to get it.
If you see anything you can contribute to the build (criticism or suggestions), let me know. The objective was to buy what was needed only once, and not to scrimp on equipment (just price!).
If you have any of the bits I need and want to sell, let me know!
For the benefit of anyone interested in the same, and for my benefit (if you know where to get something cheaper, or have thoughts on anything) here we go.. :
