Beck FTW (at least if you are interested in a decent story and an awesome soundtrack)
Haruhi is funny but incomlete
Lucky Star, Gurren Laggan and Ouran aren't out completely.
After that it's more a question of what you're interested in. Shana just came out in a box set and that is another awesome series and kinda fits along with your listed thoughts, as is Fate/Stay Night.
