You could give Outlaw Star a try it's pretty funny and lighthearted even during the intense scenes. Movie wise I do recommend Spirited Away along with Howl's Moving Castle they are both excellent pieces. Ghost In The Shell movie is very beautiful even though it's darker in nature along with Full Metal Alchemist Brotherhood. Found FMA BH to be a very good anime though I personally like the first FMA even though it doesn't hold 100% true to the manga.
One Piece is definitely a good view and you can watch it on onepieceofficial.com which is fully licensed/supported by Funimation having both dubbed and subbed versions. However the dubbed versions only go up to episode 200 I believe while subbed they come out with them regularly almost every Sunday here in the US. Hope to catch the new episode of One Piece tomorrow around 2 to 4:00 pm est once it's been translated.
