I wouldn't worry too much about the numbers as long as they sound even to your ears, too.

I don't have the digital meter, so I can't tell you which is the correct way to point it. With the analog meter, in addition to pointing the mic at the speaker, you also have to make sure you're not directly behind the mic as it may skew the readings.

I know sushi has a digital meter. He may chime in and help you out.
