If you're going for an inner frame with mechanical joints instead of a simple shell-and-elastic design you'll need to mix two completely different approaches to 3d modeling.
For the outer shell you'll want to use digital sculpting tools. Z-Brush and Blender both have great sculting tools, the main difference between them is Z-Brush having significantly better performance when working with ultra high res meshes.
The inner frame on the other hand probably needs CAD-modelling to get the joints to fit perfectly. You can either use a dedicated CAD program like Fusion 360 or Blender with the CAD Sketcher addon.
I've tried Blenders CAD addon before and it honestly was fairly janky compared to Fusion but being able to work on both the shell and frame side by side in the same program seems like a pretty big advantage here, so i'd suggest you check out Blender to get started.
Can't help you with your second question as I've never tried making something like this.

PLA should hold up fine.
