ANSYS Workflow recommendation

If I want to analyze a ducted propeller, what is the process I should use in ANSYS? I don't have access to BladeGen or BladeModeler. I was planning to use OpenProp to get a first draft and then transition to CFD. The following are my questions:

1. Should I be using CFX or Fluent for this?
2. What should I keep in mind for meshing?
3. Since the duct has a different periodic profile than the propeller, is periodicity relevant/useful or should I just model the entire thing all at once?
4. Is it worth doing transient analysis? Why or why not?
5. Anything else that I should know?
