How Do I Make An Item Easily Line Up To A Ruler Guide When I Move The Item Near It?

Click on the Snap to Guide button in the second-level toolbar to activate Snap to Guide.

Once this is active, you can drag an item on the page and when it gets close to the ruler guide, it will automatically “snap to” that ruler guide so that it aligns with it.

If you wish to turn Snap to Guide off, just click the Snap to Guide button again.
