I've not tested to make sure this works, but I'm pretty sure it will...
Right-click on your DROD-TCB.app, and choose 'Show Package Contents'. Once you're inside, go to Contents, Resources, Data, Music. That's where you'll want to put the .ogg files.
Your .ini file should be located in your user folder, Library, Application Support, Caravel, (either drod-3_0 or drod-3_0-demo depending on if you have the full version or not). You'll have to manually tell TextEdit to open it, as it shouldn't be auto-associated, but once you're in there, you can go ahead and modify as stated in the first post in this thread.
To make it easier, here's the section out of mine (though I've got some other styles installed, so check to make sure you've got all the ones I've got, and if there's any missing, strike them from this before you paste it in).
