I watched this video:
http://www.pokerstrategy.com/video/12827/

The basic thrust of the video is that you must answer these questions:

1. What odds are you getting?
2. How risk averse are you?

Throughout the example section of the video, there were many statements of the form, "<hand> has <number>% equity against a <number>% range.

Where does this information come from?
How is it calculated?
I understand the you need to understand your opponent to estimate his range, but what does a 5% range actually MEAN? The top 5% of the possible 169 hands? That translates to 8.5 hands -- so QQ+? I a 10% range JJ+ and so on?
Do you adjust for the suited/non-suited?

Are there articles that discuss range % vs what hands are in those ranges?

And finally,
How do you calculate the equity of one hand against another?
What is the input data?
What are the calculations?
How on earth can you do all this in 15 seconds!!
