The OP of this thread is asking the same questions I feel everyone asks when they just start taking an interest in this topic. Unfortunately, it's hard to comprehend that there is so much more to it.
I commend the responders for being patient in this thread in their help. But I'm not a fan of the "before you get a camera you need to..." advice, I feel when you have a camera and start doing things, that's when you really start learning.
I like the Canon HV20/HV30/HV40 as a starting point. Maybe we can make things simple and say get started with that? The reason why is that I've seen some really nice looking things coming out these cameras once the user knows what they're doing. It's a good learning camera and not too bad - I myself I bought the HV20 refurbished from the canon store for $399+tax and shipping back in April. I'm sure deals better on newer models (Which from what I understand, aren't really too much better) can be found.
