Hi there,
1) I can't help you here but there is a huge section in the FAQ section about wheel and tyre information.
2) the spare wheel is fine for any size alloy you have as it will have the same rolling radius as the original alloys.
3) It's fine to fit traditional tyres instead of runflats. You have all the safety precautions MINI recommend with non runflat wheels so its no problem done it myself!
