If you're looking for a camera but don't know too much, I would go to a bunch of stores, ask people questions, look at stuff, etc etc. Make sure the camera uses a recognizable file format. The camera I use now, as crap as it is, is a JVC Everio HDD, and it uses a "MOD" file which is some type of mpeg-2. Its taken me a loooong time to get it to work properly.
Once you have your camera, experiment. Try dolly shots, follow cam, different angles, read up on your settings, play around with them, and figure out what you can do. A tripod is not necessary, but it will help. I can make my hands damn steady when I want to lol.
Make sure that you have at least a decent editing program, such as final cut. Use your colour adjust settings, and if you have After Effects run your video through that to tweak it a bit.
I don't really know that much, but this is what I can offer you from experience.
