Some other random problems that people have had are grease streaks on the windows(most first year Z's have this problem), axels clicking while driving in reverse, a loud noise from the transmission while idling in neutral and the clutch pedal is out(the throwout bearing rattles), some grinding in the transmission when shifting(not everyone experiences this problem), the window switches stop working(rare I guess but it has happened), the cloth on the seat bolster starts to wear after time, and the last thing I can think of is when you are slowing down from high rpms, you might feel a vibration in the shift knob(this is normal). Almost everything mentioned has been address with a TSB, so you should be able to find out all the information you need on the TSB Thread.
Good luck with your new Z, I am sure that you will enjoy despite any little problems that may come up.
