I'll see what I can do. But the ones in default.aspx need to stay there because those are page-level styles. If I put them in the CSS file, they would likely interfere with existing styles for developers integrating GSP into their apps. Luckily it is only a couple, and should be easy enough for you to deal with.
I should be able to find images without too much trouble, but it would help if you compiled a list of any other issues you encounter. There should be very few inline styles in the user controls (besides image width/height styles).
