Is the normal landing a 1-engine landing? If so, is the advantage of a 3-engine landing that it requires less fuel due to having a much shorter 'suicide burn'?

Yes, and yes. The less time you're in the air, the less fuel needed to counter gravity's continual pull, so the most efficient landing burn is basically the highest acceleration you can handle without coming apart such that your velocity hits 0 as your altitude does.

What’s a “suicide burn”?
