I recommend the HV20 instead. It's much cheaper, and has almost all of the features of the HV30 (no 30p).
Basically, for starters you can white balance your camera using the basic included settings, but it's best to use a piece of white material.
This is VERY important: LOCK THE EXPOSURE. What that means is, you need to use the joystick to click into the exposure settings, set it at a point where the image looks good, and then click out of that setting... it will be locked at that point. If you don't lock the exposure, every change in lighting will affect the whole picture.
One time, while trying to shoot a video of my showcasing a camera, I forgot to lock the exposure. Then, in post while editing, I saw that every time I turned the object on it's side, the reflective silver surface created more light, and the camera tried to compensate by lowering the exposure, and so the whole picture would quickly go dark, then change back to light, then go dark again, based on my movement.
Set the frame rate to standard HDV (60i) unless you have a specific purpose for aiming at 24p (emulating a film look, but you need so much more than just 24p). If you plan to color grade your work, use the neutral or cinema color setting, it's easiest to color correct/grade dull colors rather than artificially enhanced colors.
Perhaps equally as important as the settings on the camera is having a plan. An amateur points and shoots, a professional plans and shoots. Have a plan, set it up, and get your lighting arranged ahead of time. I know people who spend hundreds of dollars on the camera and mic, and forget to invest in lights. You want to make sure that your video is well light by a single type of light (multiple sources is OK, just don't intermix light types).
I hope this helps!
