unfortunately there isn't really a way to do what you are asking for then via Access 2003. With the new A2K7 and Outlook 2K7 it has the ability to send a form (not formatted real pretty though) to accept input and then when they return it the data is automatically entered into the database.
As for sending a form to fill in the data, if you want it pretty then I think you may want to just use Excel or Word to create something to send out. Because a form can't be sent to email with the ability to fill in.
