I have a Nokia 6600. I want to see incoming calls, messages on my Mac using Bluetooth.
Use Blue Phone Elite. Works well with a Nokia e65. It's not free, but worth the money (i feel).
This allows you to send and recieve SMS messages on your Mac and also use it as a bluetooth headset.
I have just checked the compatibility list, and does not let you send SMS messages due to a limitation of the device. Not sure what this is.
You could use Apples built-in iSync, which would be free: http://europe.nokia.com/get-support-and-software/download-software/isync
If you'd like to control your mac with your phone (play music, video, start screensaver when you leave, start music when you come back etc.) I'd try Salling Clicker: http://www.salling.com/Clicker/mac/
Hope it helps. :-)
