As CraigR pointed out, you should go into your database table and set the ID to auto-increment. You would then want to leave the ID column blank in the wizard. When a new row is inserted into the database, the ID will automatically increment to the next number when nothing is inserted into that column.
There are also default values you can set for the different columns. That way if you don't insert anything into that column from an insert, it will default to that value.
