RocketFM Design help

I just thought I would throw this out there to see If anyone would be willing to help. As you know the project we have been walking through (RocketFM) needs a little more help on the UI side. If you take a look at the screen shot below its coming along nicely but I think its missing a couple of important elements.

First we really need to come up with a logo that we can use in place of the text. We can build some logic to so that if the file is not there to display the text in its place. Finally I really think the button on the bottom right stink. We should probably have some buttons along the top right aligned for download/upload/delete/about. The problem is I am not sure if we should use regular icons or come up with buttons that have a nice over/disable/click states. Any help would be greatly appreciated.
