I'm pretty new to GIMP and I'm drawing just plain black lines on a grid with snap to grid enabled, and I want to try and make the diagonal lines smooth like the others and remove the pixelated and raggedy edges. Any help would be appreciated.

How to smooth jagged lines

Gimp is a bitmap editor, so it works with pixels. Diagonal lines will show the painted pixels as pixelated and raggedy.
What tool are you using? The Pencil does not have anti-aliasing so the edges of diagonal lines are very harsh. If you use the Paintbrush with a soft brush the edges are not harsh. It also depends on the size of your image in pixels. On large images the harsh edges are not so visible. If you already have an image you can use Filters > Blur > Gaussian Blur to soften the edges. 
No really good way to remove pixellation. It is best avoided from the start using the proper techniques to draw things.
If you want to draw a straight diagonal line: - Click on the starting point and release the mouse button - Move the mouse towards the end point - Depress the Shift key, this will make a track line appear - Move to the end point (which can be snapped on guides/grid) - Click again to draw the line While moving you can also depress the Ctrl key to force the lines on multiples of 15° Another method is to use Paths.
