ViolinGuy pretty much covered it all. Can't stress the point about not stepping foot on the dock enough. Use the banks next to it and cast at it. My advice is a little different than his, but the same in a lot of aspects. Try soft plastics, spinner baits and some top waters first (warning- top water is the gateway to the obsession. You have been warned). Those three will cover all depths and situations for now. Learn and become proficient with those and then go from there. Try different presentations with each. Read these forums and the articles on the site (they are priceless when it comes to learning about the sport) and talk to other guys.
But most of all, there are as many baits, presentations, and "secrets" to catch a bass as there are trees in the forest. Learn from the articles and in talking to other fishermen, and then fine tune with what you learn in your experience.
Welcome to the obsession. Hope you slam 'em!
