A few Eagle CAD Silkscreen tips,
To move the silkscreen independently of the component when tidying up a board layout you need to use the "Smash" tool on the component or a group of them. This then shows the cross hairs allowing you to move it separately.
So the silkscreen looks the same when the board is made, be sure to use vector font, you can switch this on by going to menu Options > User interface and checking Always use vector font.
