Hey phlaw,
I'm a video producer by trade and I've had plenty of experience putting together projects like these. Honestly, the best advice that I can give you is: keep it as simple as you can.
Here are a few other considerations to keep in mind as well:
Proper framing. Keep the camera steady and follow the action. Make sure that your subject and the techniques being performed fill the majority of the frame. Proper head room, eye line, and a stable horizon line are key elements.
Make sure that you shoot it in a setting with enough light to ensure proper exposure (ie: you should be able to see the faces of your subjects) It's generally better to shoot with a brighter foreground and a darker background. It provides better contrast.
Stay away from un-motivated Transitions (I know that those page curls and wacky shape wipes might seem cool, but if they don't add to or further the telling of your content then I BEG you don't use them. They just add to the cheese factor. Basic cuts and dissolves are all you really need)
Do whatever you can to provide clean, easily understood audio. Depending on what type of movement is being performed, you may be able to get away with a wireless lavalier microphone. If you are grappling, or doing a lot of techniques that require the demonstrator to rub up against thier clothing then a lav might not work.
You can get away with using an on-camera mic if you are close enough to your speaker that the audio picks up decently. However, I would avoid it if I could. Use a pair of headphones when you shoot. They provide confidence monioring of your sound.
Editing software can be a bit daunting if you've never used it before. If you've never edited before -- as you learn keep things simple and use apps like Apple's iMovie (if you're on a Mac) or Windows Movie Maker. The Pinnacle stuff is decent too. If you want more functionality and quality then head for Adobe Premiere, Apple's Final Cut Express, or Final Cut Pro, or any of the Avid line of products (Liquid, Xpress Pro) These are more professional tools and require a considerable learning curve (and lots of Cash$$$)
Good luck with your project.
Train hard !
