How do I connect a VOICESTAR Bluetooth dongle to a Motorola H550 bluetooth earpiece?

[RONM]

I'm running Windows Vista Business on an HP Pavilion dv6700 Notebook PC with an Intel Core2 Duo CPU with 2038MB RAM.
CRITICAL: I'm taking an on-line course next week and it requires two way commo via my notebook using a headset. I thought the easy way to do it would be via my bluetooth H550 earpiece.
