Slightly OT but as someone who has studied my own habits and those of others (through observing youtube engagement data on videos that I've been involved with), I'm going to recommend that your videos be no longer than 3 minutes and preferably 1 minute in length. If it's longer, there is too much filler to make whatever point you're making and people WILL SKIP THROUGH. If you're discussing a long topic, break it down into key points (chapters/episodes) across multiple videos.
Having more videos of a shorter length will probably help your ratings and search optimization too...
As for hardware, apart from what everyone has discussed already I'd like to mention that if you already have a decent digital SLR camera, they double as a very good video camera. You'll still want to do audio separately.
