2, I think, you don't have to buy so many molds at first, just start with the basics.
You need low-gluten flour to make cakes and high-gluten flour to make bread. Just look at these two when you buy them.
Buy the simplest mold first, for example, you can buy a 6-inch round mold for making cakes.
If you choose to knead bread by hand, it's even more difficult (but I'm fascinated by kneading bread by hand ...). It's very helpful to find some videos of kneading dough by hand or Sina's food blog.
