If you don't have the #bar section in there, they won't show up >.<
If you don't want your avatar to show, you can use
#profile {position: absolute; left: 850px; top: -10px; background: transparent;}
#profile #bar { background: transparent url() no-repeat;; display: block; }
At least, that's what I did in one of my profiles. You can change the italicized content to wherever you want to position the invisible avatar. That will give you a starting point for the buttons.
HERE is an example of what I did in a profile I coded.
If you need help you can PM me and I can try to explain it to you better :3
edit: view the code I showed as an example in action
here, though it works in FF only. Scroll over the band members to see custom buttons.
