I've got more to add to your list marco..
NARUTO - Currently on air in Japan and unliscenced. It's a comming of age story about a boy and his struggle to be accepted and become the greatest ninja in his village.
Jin Roh: Wolf Brigade Liscenced by Viz. The story is set in an alternative past, where martial law rules, and Tokyo is devastated by war and military occupation. There is a revolt against the authorities and war is breaking out This story focuses on a member of the "wolf brigade", an elite force of the military meant to fight the rebels. The main character is haunted by visons after he confronts a young rebel girl who blows herself up rather than be helped by him. Thsi starts him questioning his action, his job, his way of thinking. Very intellectual movie, kinda long. So well done you will forget it is animated.
Gatekeepers- Lisceneced by Pioneer. Alien Invaders are revealing themselves among humans and trying to take over the world. Secret government organization AEGIS gathering young people with special powers to help them fulfill their objective. Pretty lighthearted and fun, has a nice scifi element to it, and is well done.
Fruits Basket- Liscenced by Funimation. A story about a girl who is taken in by the Souma family after her parents die. This would be all well and good until she discovers the Souma's are all curesed and change into memebers of the chinese Zodiac when touched by a memeber of the opposite sex. Pretty interesting, lots of interpersonal action between characters.
Saishuu Heiki Kanojo (SaiKano) Not sure if liscneced yet. A love story between high schoolers, but with a twist. The female lead of this story is also a weapon of mass destruction and is called "the angel of death". Be warned. This one is saad.. I cried at the end of ever episode.
Kareshi Kanojyo no Jijyo (KareKano) Liscenced by Right Stuf. A love story between 2 teens that have similar issues with their own identity and learning to be close to other people.
If any of these pique your intrests i'll post more suggestions later on .
