Freshwater Fishing Los Angeles

I want to start fishing and don't know where to begin?
I'm looking for advice on equipment and accersories that would be good to have. I live in Los Angeles so I have freshwater, pier and deep sea fishing all available to me. Are the reel and rods that work for all conditions or would I need different equipment for different locations?
Another question, what is the difference between spinning, trollling, casting, and spincast reels?
Purchase a book on "Fishing for Dummies".
