Yes, yes and yes. Every spread betting firm offers a different range of instruments that you can trade so you need to check with them to see what they have on offer. Some have more instruments than others and some try to specialise in certain areas. For instance some only offer FOREX and indices as these are the most commonly traded markets in the world. Some offer more in the way of Equities listing AIM stocks. As I said you need to check with your spread betting firm to get a complete list of everything you can trade with them.
