Adobe Captivate expert

I have an Adobe Captivate presentation which I need to improve: - The size of file is too much big. So I want the videos not be included in the presentation but loaded from server dynamically when needed - Also load dynamically images - I want the texts in the presentations not to be included in the .swf file. If possible, I prefer the texts can be catched from an excel file I need somebody to show me how to do it. (The presentation is offered through streaming) thanks
