I'm currently in the process of uploading 4 videos to YouTube.  The first is an intro to RepRap and the other 3 are tutorials for assembling the main frame.  As soon as they upload you will find them in the RepRap Assembly section.  These will be improved, but they do the job for right now, please let us know how you'd like to see them improved since we plan on improving them down the line.  We are working on adding forums to the site and know that they are having some issues right now, but we are working on fixing it.  They work just fine, the appearance just has issues.
