Pretty much all new cameras have those settings. Aperture priority, shutter priority, full manual, but most people just use the Program mode, where the camera does all the settings.
Shutter priority is the one that Carl is trying to get people to use at airshows, otherwise the camera freezes the prop dead, and it looks like someone threw a model up in the air and snapped a photo. They're all really nice photos, guys. Slowing the shutter down is just a suggestion to get a bit of blur in the prop, which has a nicer effect.
Aperture priority is another thing altogether - it sets your depth of field. Carl can probably explain it better, as I don't remember which f-stop limits the depth of field, and which one keeps as much of the background in focus as possible: IIRC, (correct me if I'm wrong, Carl or anyone else) the larger f-stop, such as f-22, causes the background to remain in focus, while a lower f-stop, say f-1.8, causes your subject to remain in focus while the background gets blurred?
