I need a recommendation for a video editor to do a particular job

[KaiserD2]

Hello all. I want to make a video about how to play the piano. It will feature two types of shots. The first will be me sitting at the piano talking about how to play it. The second will be closeups of my arms and hands actually playing the piano. The actual video will continually intercut the two kinds of shots--in other words, first me talking, then me demonstrating.
The additional dimension to the problem is that I would like to shoot the whole thing myself, using my zoom video camera on a tripod. It creates MOV files.
Now in theory, I could storyboard the whole video--by which I simply mean plan the sequence of clips--and shoot them one by one. The problem is that I can't start and stop the video from the piano bench, so every single clip would show me getting on and eventually off the piano bench, and those frames would have to be edited out of every one.
So, the best thing I could do, I think, would be to shoot the two parts separately, in one continuous shot each. (Or maybe two or three continuous shots)--and then split each of them up into the the discrete clips that I need to put in sequence. Then I would need to put all the clips into the proper sequence. That is the part that Corel Video studio, which I have used for other things, would do quite easily. However, I have never found an easy way on Corel simply to break down one clip into several separate ones.
So I'm looking for a program that will easily do that to .mov files. Any other suggestions would also be welcome. Thanks in advance.
