Personally, I like dealing with individual addons rather than a total UI makeover.
As far as the video goes, my comments are:
Your accent is a bit heavy, making it not the easiest video to understand.
I prefer not to copy into folders other than \interface\addons\ .
I would script your dialog a bit more carefully, and leave out the part about your hating blood elves and paladins, that your dk is **** looking, and the use of "F'd up" to describe the initial screen layout.
