I take it this doesn't come with the PC receiver connector? So, to make it work on the PC, I'll have to get one of these [amazon.com]
Yes. This will need a receiver to work on PC. One receiver will connect multiple controllers also. These xbox controllers work very well on the PC by the way. My only issue is trying to switch the controllers back and forth. The xbox does not want to let the controller go and I sometimes unplug it so I can switch the controller over to the PC (both are hooked up to the TV). There maybe a better way.
