Would the days be shorter if the earth rotated faster?

Yes they would. Indeed in past Geological times (eg the Devonian era), there were 404 days in the year. This was because the Earth was spinning a loft faster then. What slows the Earth's spin is the pull of the Moon on Earth's Oceans. This cause the Moon to speed up (recede form the Earth) and the Earth to slow.
