That makes me feel alot better. I have around 15 minutes to play with before hand so I will sort it out then.
The only other thing you need to know is how to project the image from the laptop. The projector usually plugs into the external video port on the computer. There's usually a keyboard toggle sequence that will send the image to the laptop screen, the projector, or both. Unfortunately every computer is different, but look for a icon on your keyboard that looks like a monitor. If you've ever used an external monitor with this computer it's exactly the same.
