Yes, the female is larger than the male. Also if you do not have two of the same species ( like clown fish for example), it may start out as a male, but gradually become female. Once it is female and is ready to mate, you can tell because it will generally swim vertically along one of the walls or such.

This is very difficult. It's done through "venting." The vent is the opening between the anus and the anal fin where the fish will excrete either eggs or sperm. Usually the vent is larger in females. It raelly just depends on the type. In some cases, if there is an "egg spot" on their anal fin, it means that the fish is male.
