He's tellin you to sell it back cuz if you don't already know how to hook it up, you probably don't know what your gear actually does, and it's likely you've got gear you either don't need, or over paid for it.
First, ask yourself, "What am I trying to do?". Rap music? Record your friend's band? Electronic music, techno, dance? You and your acoustic guitar? Then do some research with the links provided through his link(funny) and you'll figure out what you ACTUALLY need. None of us really know what you're trying to accomplish. I respect the first step though. You gotta start somewhere, but it's better to be focused on what you really want to do so that you'll finish. No use in starting if you're not going to finish, even if it's just some home demo. As you learn more, you'll figure out what gear you need to add or upgrade. I think you should just back up, return your stuff and start simpler.
