For the Google Adsense thing it's not really worth it unless you get thousands of views per video. You earn like a $1.50 per 1 thousand view or something like that.
It all depends on how well your traffic converts. If you get 100 views and 10 conversions (click on ads), then you might get $5. If you get 1 million views and only get 2 conversions then you might only make a dollar.
