Great spec. You'll love your car. Might I suggest a few things to consider:
* We get full leather as standard in the UK (extra PoundsPoundsPounds of course) and I think it's worth getting that. Just makes the car look/feel so much classier, particularly with the stitching.
* Sports Chrono is worth it, for the sports mode. Much more responsive throttle etc etc.
* Nav just about worth getting - a bit behind the curve in features of the after market systems though. You eventually get to like it - not sure what the enhanced system involves though.
* Bose. I ordered it with my car and like it. But worth the price? Not sure. Suggest you listen to it first.
* X51. Probably well worth getting if you can afford it - but this is only from reading the comments on this and other boards. Of course more revs = more power on a non-X51'd 997 so you can always keep the sport button on/run it harder for a similar effect (at mid range revs anyway).
* I have the MF wheel. Found I don't use the buttons much apart from very long journeys when I use the phone and so on, but I like the look.
* Definitely recommend the TPMS. I noticed as soon as I got in my car that I had a flat and then pumped up the tyre to avoid any damage to the sidewalls before going to my local repair shop (without the gunk - don't use if you can possibly help it!). Also if you're a skinflint like me, you can save $$$ on gas by keeping your tyres pumped up to the right levels.
* I think you should try the sports shifter before you get it if you can - as many have said, even the standard can be quite notchy when cold.
* If you're driving in the winter in Boston you may want to consider ordering winter tyres now, as (certainly in the EU) they only produce short runs of them from the plant. Of course if you drive a lot in snow perhaps a 4S would be safer (although you pay with handling characteristics, weight, boot space etc).
* No need for the CD changer. Just burn lots of MP3 albums onto a CD - quality fine and you get 10 or more albums at once.
* Pity you're in the US, as the other thing I would recommend considering is the -20mm sports suspension with locking diff. Really annoyed I didn't get that myself...
* Oh yes, consider the clear bra. For some reason P-Cars seem to attract stones from truck tyres like magnets.
Just some ideas - hope they're useful. Good luck with your order. Amazing machines - hard core racing heritage which you can drive to the office every day.
SoS.
