The traction control not turning off is a bit odd. You should have a light pop on the dash when you hold the button down. Perhaps the connector behind the button is not connected, has a bad button or actually has a problem with your traction control. If the connector appears ok and the button is okay then sounds like dealer time.
As for the bluetooth, as far as I am aware you either need the Nav or the Bose. If you have neither then perhaps it has an aftermarket add on or dealer upgrade. There was a thread about something similar here:
Installation of Bluetooth. . .
Both the issue you have with the car are a bit odd. I hope it wasn't tampered with at some point!
