You never mentioned a canon lawyer if I remember correctly. Do you have one? You might want to ask Dr. Edward Peters for some advice: http://mywebpages.comcast.net/enpeters/blog.htm
Also, ask your parents to be witnesses. They may not want you to be Catholic, but they know about your first wife in any case. They might help (I hope).
My Mom isn't going to help me either. She's glad I'm going church and hopes I'll one day soon return to her flavor of protestantism.
Thanks for the link. I will look it up.
