Customize/Remove Fields Displayed in Contact Details

We have very specific fields we need to add our contacts. We work in higher education and mostly deal with people from schools, nonprofits, and governmental organizations. There are a lot of unusable fields that get in the way of adding contact efficiently. For example, we do not have "personal" contacts; there is no need for there to be information for home addresses or birthdays. It would be great if we could build templates for contacts that are specific to our needs. Because right now, it takes too long to wade through unnecessary details.
