I'm going to prom with my crush, advice?

We're not too close, but we're in a lot of the same classes and talk. I asked him to prom and he said yes! I want to go out with him, but I don't really want to make the first move again... What can I do to get the message across at prom? If I kiss him on the cheek at the end should he get the idea? I'm really clueless, I've never dated anyone.
