"I need to be able to slowly rachet down the convergence thresholds until my Vnew data is no longer changing."
worry me. Numerical analysis is not my strong point, but I am more and more concerned about the direction the code is going. You have (roughly) arbitrary precision calculations going on and you want the results to stop changing.
I have attached the code I was working on. If you open Mathematica, read the file in and evaluate it then you should be somewhere close to what I have.
Do what you can with this, but I think I am near the edge of being able to provide sound advice now.
