If the starter is turning slowly, the first thing I would do is have the batter load tested. Most parts stores will do it for free. The reason I say this is because it sounds like it is basically dead. Keep in mind, the lights on the dash require little power to light. The starter places a heavy load on the battery.
Here is a guide to help confirm the battery failure.

As far as the alt, if the light wasn't on when the vehicle was running, chances are it isn't the problem. However, once we get it running, we can check that.
