hmmm i'm not at home so i can't really help that much. You really should just be using the Desktop manager to connect to the phone. I would verify that you can do it via the USB cable first and then start from there. Good luck.
NP did you get it working? I know once you get in the desktop manager, options there is a drop down box that will let you select USB or bluetooth. I personally dont use the bluetooth becuase it eats up the battery on the phone. I also charge the phone when i sync it and move MP3's over.
