Bob,
First off, re the handling - it will take you 6 months to learn the foibles and really start to get the best out of the car... Ohhh yeah, congratulations BTW

Now:
1) usually a setting in the electronic speedo - your dealer shoudl be able to sort this
2) hmmm, I suspect a connector isn't right somewhere there - again dealer should sort this for you (they should have done it before you took delivery - to not notice such failures on a PDI isn't good!)
3) round ones are much better (not that I have any - I seem to, almost, fit with my originals
4) again dealer should sort that
5) & 6) as 4)
7) err think I've answered that above
More questions? Ask away!
Cheers,
