I've made a few videos and I am setting up a YouTube channel.

I plan on doing more videos in the new year and I have some questions

First I am using Faststone Capture to do the screencasts and I am happy with that, but I'd like to do some editing and I am looking at an app called Video Pad. Does anyone else out there have experience with this? Or do you have recomendations for something else?
Basically I want to be able to cut out portions(the mistakes ) ) and join clips together, and perhaps add some sort of intro.

Second I am looking for ideas on what to cover. I am thinking of some small but complete projects. What kinds of things would you like to learn?
