It's now too late to edit my question, but I already realized that the size and location difference between the geometry and mesh is because I didn't scale the geometry by 0.001 as is done in the tutorial. And I know you can generate an initial mesh from gmsh or another tool.
My final questions are still open regarding the what to consider in order to generate a "good" initial mesh element file.
