If you attach a bluetooth connector it should function with any
bluetooth device, even if that device came with its own connector. I've
heard many people for example say they bought a Logitech or Microsoft BT
mouse and it worked as soon as they turned it on without using the
included adapter.
And I don't see any reason to think a bluetooth adapter would make your
computer run slower. Ultimately the computer treats it like any other
USB device.
As far as "how many devices", I really don't know what the max is.
