What tools should I carry in my tool bag and are there any classes out there to teach me how to work on my bike?

I was wondering if anyone could give me a list of tools that I should carry in my tool bag? I asked where I bought my bike and they kinda gave me the well you need this and that and we can sell you the tools and that will be $250. I don't think so! Walmart is much cheaper.

Second question: Anyone heard of maintenance classes to teach me how to change the oil, spark plugs, and what to do if my bike breaks down. I don't have a guy around so any help would be appreciated!
