I would offer you some good music files from modarchive.com, but seeing how hard it is to find a good song from that site I'm not too willing. Also, you might just want to focus on making 3-5 really good battle levels instead of 7-10, unless you're one of those people who like to set high goals but tend to fall short. As for tilesets, as FireSworD said, if you make basic eye candy with the Egypt set it can't possibly look bad. It takes a while to get used to, but you might as well give it a try. If you're still frustrated, Jungle wouldn't be a bad choice. Or maybe you could use Disguise's BoredSet or something.
