As for replacing the arrows: the arrow image is a background property of the link inside the LI element. If you placed your gloss.png as the background of the LI element itself then it should work ok. Give it a try and report what you found here, okay?
looks like one background image is overwriting the other, will try some research. The arrows and shadows do not work now in the BETA so it might be something I am doing that is breaking both from showing up at the same time.
