I'm not sure I can answer your questions, but I have a suggestion. From Maxwell, you can simulate the inductance, series resistance (thus giving you Q factor) and mutual inductance of your two coil system. Once you have L1, L2, Q1, Q2, and L12, you can simulate the whole system in a much more efficient circuit editor, like ADS or PSPICE, and add on all the capacitors and loads and anything else you could want. Trying to actually get power transfer from Maxwell or Simplorer is certainly possible, but sort of overkill.
I believe its best to use FEM solvers to get circuit parameters for your system, then just model the circuit.
