Airport Extreme - yes!
Bluetooth - yes, but not with the BTO (built-to-order) Bluetooth that Apple provides (that's not available separately). You would have to go for a USB Bluetooth adapter like the D-Link DBT120 and connect it to your USB port - it costs around US$30-40.
But if you're looking at bluetooth in the near future to use with a wireless keyboard/mouse, then the BTO wireless keyboard/mouse option from Apple seems to be a good deal for $99. Getting these separately (even non-Apple brands) could be expensive.
