Lens tests just have to be on a solid tripod, and even then several shots should be taken just to make sure.

If you use a ppi of 72 that will be a huge image, if you use 300ppi it will be smaller, but the number of pixels will not change.
When you change the number of pixels to achieve the print size you want, then you are interpolating (making up pixels) to change the pixel count.
The only two ppi figures you need are 72ppi (screen, web, projection) and 300ppi (print, publication) and although you could print at 240ppi there is no need to use this fairly random figure. The 300ppi relates to what the eye can perceive, and doubling that to 600ppi makes for bigger files but no visual difference. Halving to 150ppi gives a degredation that is visible to the eye.

For publication, the same 300ppi files are used, which is very convenient.

As regards other settings, centre spot focusing, maybe sharpness +1 if you like very sharp images, but it's all very much to taste. I'd go with the defaults for a while and see how it goes before making changes that might not suit your own vision of your photography.

If I don't win an item I don't really care who has.
