I've been trying to find a good anime or manga that I haven't already seen/read. The followings are the ones I already know:

InuYasha
Fullmetal Alchemist
X/1999
The World of Narue
Chobits
Tsubasa Chronicle
Cardcaptor Sakura
Naruto
Shonen Onmyouji
Wish
D.N Angel
D. Gray-Man
YuYu Hakusho
Maison Ikkoku
Flame of Recca
Witch Hunter Robin
Ranma 1/2
Rozen Maiden
Zombie Loan

and a few more tons of others =)

Anyone have any suggestions as to what I should read or watch next?

Trinity Blood manga. The anime was done too soon and it doesn't follow the story as well. But the manga is awesome.

(assuming you haven't already...) >.>'

I'd also recommend Zettai Kareshi (Absolute Boyfreind) - it's a Girlie manga, but I liked it anyway. ^_^

Addicted to Curry is awful cute, too.

And, Hellsing. If you don't mind seeing lots of violence and blood. I laugh when people get decapitated, so this was fine for me.

You assumed correctly. I haven't watched or read Trinity Blood though I've heard of it.

I'll try and check out Absolute Boyfriend and Curry. Thanks for your suggestions.

Saiyuki is pretty good, manga more so than the anime. Um FATE/Stay Knight was an okay anime, Rental Magica is pretty good too. There's just so much out there that I could list

I'll try checking those out too. Thanks for at least posting these few titles =)

I have a few suggestions.

Manga:
Godchild
Dark, gothic, horror style manga. Very enjoyable, and the series just ended with 8 volumes.

MeruPuri
Comedy/romance/fantasy manga. Short but very sweet.

Anime:
Majin Tantei Nougami Neuro
An interest, but different mystery series. :]

Higurashi no Naku Koro ni, or the english title: When They Cry
If you don't mind extreme gore, this series is another good mystery/thriller.

XXXHolic

Manga:
Seconding MeruPuri and xxHolic
Kitchen Princess is good for some fluffy shoujo with cooking thrown in. I'm also in love with the comedy of Hayate the Combat Butler.

Anime:
I loved Hell Girl (Jigoku Shoujo) to little tiny pieces. It's kinda suspense and horror but with an aweomse concept. If you want more comedy I would suggest School Rumble as a schooldays comedy.

I second the recommendations of Higurashi no Naku Koro ni (When They Cry) and Hell Girl! Awesome anime. <3

As for my own thoughts... As far as anime goes, I'd recommend Manabi Straight! if you don't mind a sort of... slice of life school anime where there isn't much action. It's really cute, though. ^ w^

And, for manga... I'd recommend Loveless and Vampire Knight. They're my favourites right now.

I would recommend Azumanga Daioh ^^
It's a good anime when you're bored xD Totally random and just funny =3

Seconding Higurashi no Naku Koro ni and Jigoku Shoujo (Hell Girl)!

And I'll recommend Elfen Lied...

Although knowing your favourite genre would help... xP

Wolf's rain anime or manga, dragonball z, Lovehina manga, detective conan...

For anime, I would recommend: Code Geass: Lelouch of the Rebellion, Darker Than Black, Bokurano[if you're okay with everyone dieing xD], Muteki Kanban Musume[if you like funny], Samurai Champloo, and Tokyo Majin Gakuen Kenpucho: Tou. Unfortunately, I haven't read manga in a while so the only one I can remember is Tenjou Tenge and Dragon Drive >_<

Manga I recommend.. hmmm..

Saiyuki -- AMAZING.
