That's because those videos are probably encoded with flash, which does not work on iPads. Your only real option is to look into browsers that support flash, such as puffin, skyfire or iswiffer, or use a youtube app to watch youtube videos. They have one for th iPhone, but the third party app Jasmine also got good reviews.
as to facebook, I'd recommend the app but it's gotten very mixed reviews, so you may want to look for third party apps.
