Answer 1

SQL Server datetime datatype has range: January 1, 1753, through December 31, 9999
.NET DateTime datatype has range: 12:00:00 midnight, January 1, 0001 Anno Domini (Common Era) through 11:59:59 P.M., December 31, 9999 A.D
You can use SQL Server 2008's new datatype: datetime2

Answer 2

That happens when you have a DateTime that you have not set. The .NET DateTime.MinValue is '01/01/0001 00:00' and the SqlDateTime minimum value is the 1753 value. Just make sure that none of your DateTime's remain unset before sending the data to the database.
UPDATE:
In the method you have defined, add some logic to find and fix DateTime.MinValue's that are passed to you. Please accept my C#,
if (theDateTime < SqlDateTime.MinValue)
{
theDateTime = SqlDateTime.MinValue;
}
