Hi mmcgrath,
You actually aren't going to see the Title field on the New Lead screen because this screen is based off the Customer table. The Title field is linked to the actual Lead Contact, not the Lead Customer. To help explain this further, from Method edit an existing Lead, then scroll to the bottom of the screen and select the Contacts tab. Choose a Contact and click edit, you will notice a new pop-up screen Edit Contacts, the third field down is "Title".
I hope this helps with your Customization, if this is still unclear just let me know and we can expand on this.
