Styling text on V2 Buttons

I am using the V2 button component and I have successfully skinned it via an AS script but I can’t see how to style the text on my buttons so that the color of the text changes on rollover. I also can’t see how to position the text on the button rather than allowing it to center itself on the button. The button is very wide and the text should be close to the left hand side. I’m hoping that someone with a deeper understanding of the component architecture can point me in the right direction.
