Look, I read the posts on here and can tell you that the guerrilla way is really popular these days. I would recommend a high end prosumer camera from BHphotovideo.com, a firewire driven laptop, some flourescent soft boxes, a high quality microphone and mixer, a fast laptop, wired connection to the Internet (not wifi) some time to practice and Vidblaster as your broadcast console which you or an assistant can manage very easily.
For the sake of full disclosure I will tell you that I am a re-seller of Vidblaster and would be happy to help you. Just let me know. And I have searched the world for equipment and can direct you I think to the most effective and reasonably priced.
