Toss me a .psd of the buttons you're using.
Better yet, it looks like you're using mostly layer effects; I'll pull the color you're using out of the image with my color picker, and remake it, then scuff it up four or five ways for four or five different buttons. If you're going for Fallout style, maybe a chisel bevel would work better?
Won't be able to do anything until tuesday, though.
