I want to record myself playing

[salloch]

Any recommendations for a "record yourself playing on-line" set up?

I need:

A PC Camera
A lapel microphone
Software for recording my desktop (must be able to only record a selected portion of the desktop)
Possibly a heart rate monitor as well, one that displays my heart rate on the desktop

Any one ever done this? Any recommendations for any of the above components is appreciated. If you have experience doing this or attempting it, I'd like to hear your thoughts.
