You've already added every other option so why not these? Automatic Highbeams isn't that great in my opinion but I assume you are ordering it.
I would get 6NF, Smartphone Integration, without any hesitation if you have an iPhone. I like it so much if I get a Mini daily driver I will get it on that too. You pop the phone in and you have charging, antenna, and iPod function just like that. Sure the iPod cable gives you almost that and the phone operation is Bluetooth anyway but this cradle option is sweet. And yes the ability to access the external antenna, even though it's through a passive radiator, seems to work.
I would get the alarm because even with the coded key technology someone might still mess with your car, in your own driveway too perhaps, and $400 might make a bad situation a little less bad.
