Princess Mononoke and Howls Moving Castle are my two favorite Ghibli joints.
As for manga and anime. Bakuman is pretty cool, just recently got an anime I think its up to like 10 episodes now. anyway its about two jr high school students that decided they are going to become mangakas (manga artists) the process of how manga is made with a decent bit of side story, not particularly deep but still a really good story also if you like Death Note its by the same author.
1/2 Prince is pretty silly but if you have played any mmo which seeing as you're reading it here would be next to impossible to not be true. It's a Chinese (I think) manga about a girl who starts playing a game called Second Life. only 47 or so chapters at the moment but there is a lot of humor and action. There is some character to character battle but it's usually very quick. No anime for this one just a manga.
Beck Mongolian Chop Squad. The anime was decent, but the Manga was much better (as is usually, though not always, the case) about a bunch of kids who form a band their trials and tribulations on trying to make it big. Also some romance.
Read or Die. The movie was good the anime was meh. About a secret agent working for British intelligence that can control paper, has to save the world ex cetera.
Tegen Toppen Gurren Lagan. Anime haven't been able to find an original manga yet. It's ecchi and mech oriented its basically a gag show and just becomes more and more ridiculous as it progresses.
I'm not a huge fan of Bleach or Naruto. The pacing for the stories in both is awful pretty well all the time.
On the flip side of that though I absolutely adore One Piece. If you think its just a basic battle manga than you are sorely mistaken. A lot of the humor is priceless and there are scenes that I'm not going to lie made me tear up.
Berserk the manga is awesome. Most people that just watched the anime are missing out because where the anime ends is where the story really starts. Claymore is pretty good as well and suffered the same fate with anime that berserk did, but the pacing is slow. Both being a monthly release doesn't help that but I feel that berserk has the better story.
And Fairy Tail isn't bad by the same author that did Rave Master. though I do prefer Fairy Tail to Rave master.
and for straight up comedy watch Golden Boy or Those Who Hunt Elves.
