This question has multiple answers depending on your frame of reference. Generally it is accepted as 27.3 days but scientifically speaking that's not the only measure. I've included a link to wikipedia on the subject. I'm not a big fan of wikipedia but the article is a good reference.

You've mostly figured this out correctly yourself. The Earth is much closer to the Moon than is the Sun, so it has a much stronger gravitational effect. Actually, the Moon DOES orbit the Sun, in a very wobbly line. You could think of it as the Moon orbiting the Sun and then being pushed and pulled by the Earth so that its path is like a sine wave. The expansion of the universe is only relevant on the very largest scales, between galaxies and groups of galaxies. At close range, gravity is much more powerful. This explains why galaxies frequently collide with each other. Even though the universe as a whole is expanding, gravity can pull close galaxies together so that they collide and interact.

I agree with the 28 and 27.3 day answers. Basically it is one month. That is where the word "month" comes from. It is a "Moonth", or the time for the Moon to go through one cycle of phases from full back to full again.

About 2,382,000 kilometers. It's a little bit different every time.

27.3 days, the same amount of time its use to rotate once.
