About the music... that is something personal, it will give character to your game, so I think you need to chose it yourself.
Personally, I'd go for chiptune-eske music, but something not that old and retro, maybe a IT or XM module. Myself, I like an upbeat rhythm like Oberheim Power remix by Phantomas (opower-rmx, which I can not find on the web anymore)... and if I could... I wouldn't know if it is allowed by the author:

But ask L0ra for music...
