Holy crap another Prince George person! Welcome to Canreef
There is a lot of information on this site and plenty of people to answer your questions. However its best to read a good book first before you really get into this. The Conscientious Marine Aquarist by Robert M. Fenner is a pretty popular one. Reef Keeping Magazine is another great source for information as it is composed of lengthy in depth articles on nearly every subject you can think of

There are two retailers in town who carry saltwater: Total Pet and All Clear Aquarium Services (a home based business). The sponsors on this site can also ship you anything you want. Most of us with established tanks trim our coral regularly so there is also a never ending supply of local coral fragments available.
