I maintain a list of programs and web 2.0 services on my conference web site, on which I train participants who attend my workshops: http://nysahperd.org/conf/conf10/rfisk/Software.html . Also there, you will find a variety of interactive video tutorials (created with Camtasia/Jing), templates, screenshots, and other tech tools and tricks for educators.
