Well, you've got a whole world to explore. If you want to keep going with the Clannad/Lucky Star kinds of anime, the next thing you should watch is the Melancholy of Haruhi Suzumiya. If you want to try another racing-themed anime, check out Capeta.
If however you'd like to dabble in broadening your horizons:
Fantasy adventure: Moribito
Psychological robot drama: Evangelion
Samurai action comedy: Samurai Champloo
Awesome epic movies by Miyazaki, touching, incredibly good, lots of coming of age stuff, start with Spirited Away
Dark comedy, otaku, slice of life, Welcome to the NHK
But probably before anything else, Space Western Action and one of the best animes ever, Cowboy Bebop!
