Regarding the CD Player:
I've never done it in a Subaru, but I have experience in taking apart the factory CD changers in a few other vehicles, and it's likely that the disc selector has passed by the last point stop in its track. You can take it apart and usually fix it, but it's super tedious and you have to pay close attention to the springs and screws as they all have to go back in the same place. It might be better to replace it at this time. I hope that helps, even a little bit.
Regarding the lights:
I don't know that there are any really good alternatives to upgrade the lighting that actually are any good. The Sylvanias are okay, but they won't give as dramatic of a difference as they advertise. You'll be better off trying to retrofit TSX projectors and convert to HID. (Or you can go with STi headlights instead and get a similar effect.) Good luck, man.
