1) You can put the textures and geometries in the new runtime. Some people prefer to keep them in the main runtime because there are products for different characters that share geometries or textures. For example, a dress package that includes dresses for V3, SP, and the Girl, that all use the same textures. It's kind of a waste to put the textures in each runtime, if you have separate runtimes for each character.

3. That should work. See the link for a previous discussion on ways to organize your runtimes.
