1. You can definitely use the headset with your laptop. That's what I'm doing.
You shouldn't need any additional software so long as you've already got the Bluetooth drivers installed on your computer. If your computer came with Bluetooth then I'd imagine it came with the drivers preinstalled.
2. Yes, you'll definitely be able to use it with your phone. Should not be a problem at all.

Strange. Hasn't happened to me - it stays paired fine.
