After pasting the html code from picasa, you have to paste this "wmode="transparent" after the height and width, and before where it says flashvars. This should make your flash transparent and allow all css to rule up front!
Ps sorry about the spacing of this font.....it is my next problem to tackle (changing the blog font only, not the whole site)
