If you are planting at the correct depth ie 3 times the height of the bulb above the top of it then you there will be no problem. It would be a very hard frost to penetrate that deep.
Why water? Unless you are in an incredibly dry place then there is enough moisture in the soil for the bulbs to begin growing. In any case watering would increase the risk of frost damage. Just plant them.
