I am having a really hard time with my user defined fields on a
customer form located in my Organizational Forms Library.

Is there any way to
1.) Find out where they are located.

The field definitions are located in the form design or a folder or both, depending on how you created them. See http://www.outlookcode.com/d/fields.htm

2.)Edit an already existing field?

You mean change the name or data type? No.
