1) I don't know about docks... get the one with an extra battery and USB.
2) If the price difference isn't that big between the FIREGL and the 9600, I'd get the FIREGL.
3) Centrinoes battery life is outstanding, I'd go with that.
4) Well, you're probably going to need a wireless network...
5) I don't think so...
6) The speed difference with 100MHz is completely unnoticable, unless there's some FSB change in there. I'd go with the 1.7GHz.

Darn you spongie, you beat me to it.
