I've read that widescreen games keep rendering 640 pixels horizontally by making them stretched rectangles instead of squares. Is this the case? (If so, does it mean that widescreen games are always somehow scaled when displayed on a square pixel display?)
Yes. (Actually, the pixels are non-square even when in 4:3, but they're even more non-square in 16:9.)

One solution I came up with was to force a 4:3 aspect ratio (thus making the image taller) to then squeeze the image vertically with monitor controls.
Does this make the image use all 480 lines or does it just stretch the game incorrectly?
If you want to play on a 16:9 CRT, then my recommendation is: Set Dolphin to Force 4:3, do not enable Crop in Dolphin, and set the TV itself to stretch the image to 16:9.
