Clay, I would not venture that far as a beginner. Video set ups are quite a complicated thing and for a beginner slightly over the top. Not only the above set up but then there is the whole issue with audio, which is not yet included in Terry's set up. Sound is equally important to the video aspect and equally expensive! (I have a full set up but mostly use my dedicated semi-professional video cameras)
I would just get a feeling for shooting video with your camera first, then venture into editing (another huge step!) and once you have accomplished those two you can think about whether you want to invest the $1000+ (including audio set up) or whether you are better off with spending that amount of money for a good camcorder.
You can get spectacular video with the above set up, i.e. a shallow depth of field that you could not get with a consumer camcorder, but the learning curve is steep. You can get faster and betetr results as a beginner with a camcorder that has a certain amount of manual settings.
Anyhow, just my two pennies!
