Please help fix, test and optomize a complex plugin

Hello everyone. I just started working on a rather complex plugin and I really need help from WordPress/PHP experts. Let me describe it. It is based on code that am using in a project that was originally not WordPress based. I went ahead and worked the code into a compact WordPress plugin when the project moved to WordPress. The plugin uses a Flash mp3 jukebox and allows the user to upload mp3 files and manage their playlist, which is an XML file that the Flash jukebox uses. So upon activation the plugin creates a table in the database and a folder in wp-content. Then it creates an options page under “Manage.” The user can then go to the manage page and upload mp3s. When they are done uploading the mp3s they click a button and the plugin updates the XML file for the playlist. Then they just put a function in their template that links to the jukebox which plays the songs.

All of this functionality works on my WordPress sandbox. You can see it in action at:

Just click “Jukebox” under “LOOK HERE.” Unfortunately there are some problems and there is more functionality that needs to be added. Please let me know if you think you can help. I can send you the files so you can install it on your WordPress sandbox and maybe help with the problems. Thanks in advance!
