I could shamelessly plug my
GUI compilation...
... or suggest some "really great to have" druid addons... like DruidBar, some good unit frames (I love XPerl), and good raid frames like XPerl or Grid. And/or a HealBot mod. A barmod is great for shifting bars when you shapeshift. My fav is Trinity for full power control, else Bongos2 or Bartender3 for easier setup.
