Answer 1

Yes, that is one way to do it. But you can also do it by doing some simple math. For instance, let's say the you have an image that is 4000 x 6000 pixels. It doesn't matter whether resolution setting is in the file. The image is still 4000 x 6000 pixels. But you can decide what resolution you are going to export your copy. And you would do that for its intended purpose. If you are going for a high quality print then you would probably want 300 PPI in your export settings. With the example I've given the size print you can get had 300 PPI would be as follows:
4000 (pixels) / 300 (PPI) = 13.333 Inches
6000 (pixels) / 300 (PPI) = 20 inches
So if you were really precise in needing a 300 PPI print you can get one that is 13 x 20".
If you are preparing for display on the screen, the higher resolution isn't needed. Using the same math:
4000 / 72 = 55.55 inches
6000 /  72 = 83.33 inches
By doing some simple math in your head you can determine the resolution that you need and the size that you need and set up your export accordingly.
Technically speaking a digital image doesn't have a size other than pixel dimensions. Everything else has to be determined by the resolution that you need for the intended purpose of the final image.
