If gravity is about the same as on earth then the planet is less dense. This is possible, within limits, see ardeegee's chart. There would likely be less mine-able metal.
The Moon has a huge effect on the length of the day (slowing down Earth's rotation over time), and a Moon as large is ours is thought to be rare. So I would say that the day would more likely to be shorter than longer, but "about the same" is ok because there is so much variation.
