US models of 9x6 series came w/ a spare, tools and a jack. 9x7 US models (which stated w/ MY'05 and is what you have), came w/ a can of goop, electric compressor pump, tools, gloves and hearty "good luck" pat on the back. A few guys on 6speed w/ 997s added a compact spare (from 996's) as a piece of mind for what it's worth. I just carry the OEM goop & pump along w/ a plug kit in my 997 [fingers crossed...]
Good luck and enjoy your new Boxster!
