Multithreading is already implemented and just needs to be used some more. That’s for all games not just yours.
Hardware skinning will not be neccessary for your game since the isometric view implies that you have quite a distance between the camera and your scenery leading to the possibility of using lower polygon meshes and lower resolution textures. You don’t need super high quality characters if you plan an isometric perspective.
Btw: If you want to show your product you can always upload some screenshots 😀
