Love the Get Up Kids too - Actually saw them a few weeks ago supporting Jimmy Eat World (another favourite, and their Clarity album might be my favourite 'emo' album)
Have dipped into the Wonder Years a little (mainly their Sister Cities album) but need to explore a little more
Love Thursday, Refused and ATDI too - Some other favourites would be Appleseed Cast, Cave In, Saosin, Copeland, Pedro The Lion, Dismemberment Plan, Elliott (their 'False Cathedrals' is a forgotten masterpiece), Far, Fireside (The Swedish Quicksand), Glassjaw, Helmet, Kevin Devine etc
