Between that and the fact that the Moon rotates at a speed that means it always presents the same side to us, I don't know what's going on.

Eh tidal locking is decently common

This is really great piece (with graphics) on how the moon became tidally locked (always the same side facing towards Earth) and why it's quite common

The moon is tidally locked.

It was spinning at the start and then slowed down because the earth's gravity was causing the shape of the moon to distort. This bending caused friction so the Moon bled off its kinetic energy as heat until the system reached the current equilibrium.

Yeah, tidal locking is CONSIDERABLY more common than eclipses are. Every moon in the solar system large enough to be round under its own gravity is tidally locked to its respective planet, and even Mercury experiences a form of tidal lock (albeit in a 3:2 ratio than a 1:1 ratio)

Tidal locking is actually fairly normal to occur over (a very, very long) time. Not really a coincidence, just typical forces at work. Lots of moons do it.
