RE: What order should I buy these tools?
Not really especially with small stuff. The reason the bigger belt sander has more power is because it is used for bigger/tougher wood. My friend is a carpenter and he had a belt sander like I have. He sold it to me and bought one like you are thinking about buying and he told me it works great for him because he works on cabinets and the like. The one I bought from him works great for me because I work on small stuff.
