Found this little gem the other day that helps with a bunch of layout and player options to make youtube a lot better.
You can center everything on the screen getting rid of all that unused space on the right, disable ads, switch the player mode from flạsh to HTML5 so it'll actually buffer while paused, you can set the default resolution you want and how the player looks. Tons of useful stuff.
It's available for chrome firefox and even safari.
