I'm into the "Stained Glass Bluegrass", as the list shows. I'd recommend the same set as TopDown, but also go onto www.pandora.com and register. Try the Country/Bluegrass station. That will give you ideas about all sorts of bluegrass bands you've never heard of, and probably a few that you have.
When it comes to bluegrass, there are some groups you just cannot go wrong with for starting a collection or for picking songs to learn:
Bill Monroe
Johnson Mountain Boys
New Grass Revival
Earl Scruggs, or any Scruggs family member really
Seldom Scene
If that doesn't get you off to a good start on a Pandora station to hear and bookmark more artists, I don't know what will. Listen for what turns you on, and then try and learn those songs. For me to tell you which ones are good to learn is tough (though I tried with the few songs at the top). But listen and hear what you like, and it'll come together a lot better for you, I expect.
Good luck and have fun.
