I don't see why you'd find the graphics cells to be square. That's not
my experience and it's easy to set a certain aspect ratio:

Plot[x, {x, 0, 1}, AspectRatio -> 1/10]

Any picture that I import is shown in its original aspect ratio. So I
really don't understand your problem.

Your editing of the .nb file in a text editor seems unnecessary. You
can set all options using the option inspector in the Format menu. The
aspect ratio can be set in Formatting options/Expression formatting/
Graphics Box options/GraphicsBoxOptions/AspectRatio.
