I got my tonneau cover from Paul in the forum http://www.350z-uk.com/forum/viewtopic.php?f=38&t=13443 and it's great.
Got a Pug307 luggage net from ebay last week and it fits perfectly. http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=390049302533
Unless you had an ECU update, all European 350s are restricted to 155 in both 5th and 6th. Martinmac has a different ECU, not sure if his is limited or not.
We had a hornet in the lounge last year, all be it a sleepy one as it was crawling across the floor and not flying - quick shot of RAID Wasp killer and a whack with a trainer sorted it out. As Madmarkie said, about 2" long and bloody scary.
