I would continue to back off. At this age, it really has to be her gig, not yours. By the way, it always was her gig. I disagree completely that you can actually "potty train" a kid--they have to be able to do it on their own.
Look at it this way... this is one of the first areas where she had/has control over what is going to happen. As you know now, by trying to take that control from her, you set her up a little bit. Now that you've backed off (have you?), you can enlist her help. "Oops, I noticed you didn't get to the potty on time. How can I help you get there sooner next time? Should we have potty times during the day, just in case, or can you do it with out the potty times? You're such a big girl now and I know you can do this!" Of course, you are saying all of this in a matter of fact tone that turns encouraging at the end with a big smile.
This is all a matter of attitude, I believe. I got caught up in the fact that my oldest was potty training herself at 2 and my younger daughter would still have many accidents at 3 1/2. My friends all did different things and I felt that my kids were "behind" both times. By the way, I have a 14 year old and a 12 year old now who are obviously potty trained (wait until periods if you really want something you have no control over!). I know it is a tough time, though, when you feel like it might be willful.
Let her fly the plane. You can be her wingman.
The night-time wetting, I might get an opinion from the doctor on that. Sometimes, though, that's a physical maturity issue. Is she helping to change sheets when needed? Be matter of fact and cheerful about needing her help...
Matter of fact, cheerful, encouraging--it will happen.
