WMP Skinning Help Required

I am construscting my first ever WMP10 skin but i've kinda got stuck with fine tuning the codeing. Firstly how do you customise vizualisations. I want to make the Bars effect have a transparent background and make the bars and the little dashes at the top of that bars black. How do i do this? Secondly when your in WMP10, when your playing a song and the bottom bar next to the controls the text displays the status, then the track title, album and other track details. These keep switching between the other in a constant loop. What is the code to get this to work?

Any help would be appreciated.
