If you have a capo try playing Take My Hand by Shawn McDonald, it's a really interesting song to play, I mean the actual chords and stuff aren't but there's slapping and what not involved.
Also give Interstate Love Song by Stone Temple Pilots, it's a decently easy song, and there's a really gnarly youtube version of it that I've been trying to figure out.
