at 11 years old, that list is no great surprise, and really doesnt sound that bad.
Get the actual broken bits (lights, spoiler switch) and the MOT advisory (brake pipe) fixed under warranty.
Put the consumables (brake discs) down to experience.
And expect the the worn out but still working items (air con/cat heat shield,coil packs) to fail in the next couple of years along with some other stuff that you dont yet know about, it is after all an 11 year old car, things are going to stop working.
I wouldnt expect the EH warranty to be worth the paper its written on, but that could just be me being a massive cynic.
