So are you basically just making structural changes, as in reshaping, at this point or are you recutting the mesh and so forth (as in changes to the number of vertices, etc)?

Yes, true that.  It is hard to develop for a figure that is in flux.  No figure is without flaws and as long as you have hit your design goals to the best of your ability, you can sit back and be proud of that accomplishment :)
