Featured Slider Text Boxes

Couple of questions about the text boxes on the featured slider? How can I change the font sizes for the header text to be one size and the post text another? Can I set a fixed width for the text boxes? Is it possible to remove the shading on the text boxes? Can I set the position of where the text boxes are displayed on the slider? And finally is it possible to position the next/previous pips at the bottom of the image to the right? Many thanks.
