Re 2: No, you cannot make the Datasheet title row to be 2 rows tall.
Re 1: You can simulate a check box with a text box that displays a Wingding
character, and then use Conditional Formatting on this text box. Details in:
Format Check boxes on reports: size, color, unbox, conditionally format

If you actually need the user to change the value in the check box, you may
need to use the GotFocus event of the text box to SetFocus to a real check
box that was previously behind the control (Format | Send to Back) and had
its TabStop property set to No.
