Well,... Aside from answering favorably to points 1. and 2. in case you are inclined to, I think you have to accept that phone calls are pretty much an unavoidable step in a relationship that starts in this way. It would probably be a very bad idea to flatly reject phone calls, unless you are not interested in her.
On the other hand, you are totally entitled to voice your opinion on how the phone communication should be handled. And she even seems ready to listen to your needs.
So you have to think about what would be comfortable: call once a day, or once every three days? Mostly do text messaging, and save long phone calls for when you really have time and inclination for it (like once a week). Only make a phone call after you agreed on a time (a bit like a date), etc. It's your call. Just pay attention not to sound too arrogant when you voice your preferences, you are simply trying to improving the experience.
I would also mention your (bad) past experiences with phones and relationships, to show what you want to avoid, but do tell her that you look forward to speak with her, otherwise she might be intimidated. She has been pretty open with you, so why don't you return the favor?
