So.... just out of curiosity, what Mac do you have? What's your situation? Tell us if you've got it working yet.
Oh, and, also of note: If you have a built in-receiver thingy, or once you get an external one, that receiver can be use for all your bluetooth devices at the same time...
Sorry. Don't mean to be so thourough. Have no idea if you're a complete newbie or what.
