Hey John,
You can create a custom view in the Field Management section of the Admin tab. Click the tab "Custom Layout Designer". There, you will be able to drag and drop the fields you would like to see at a glance. Note: this creates a new page when you view a Lead/Contact Record. Meaning, when you double click the record, this is the first page that will appear so I would recommend adding the basic info (Name, email, phone, etc.) on your custom page as well.
