Request for Japanese media recs: Or, I'm Fricking Crazy.
Since every time I've come to you guys for assistance you've blown me away, here I am again, on my knees.

I'm one of those few, those happy few, who are taking the Japanese Language Proficiency Test come December. I'm soooooo not ready for this. I am only taking 3kyu but I'm really not at that level yet, and I have two months to haul my butt up to the point where I can really comprehend it. Part of the trouble I'm having, I think, is that I work at a library and am constantly finding delicious things to distract me. And worse, I think, is that I'm just not comfortable with what I do know. If I've had a couple of shots, I'm evidently much more fluent than when I'm sober, so I know it's there, I'm just too anxious to get at it normally.
So I've made myself a goal; aside from Halloween, which is my birthday, the six weeks leading up to the JLPT will see me consuming no media whatsoever that is not Japanese. No TV shows, no movies, no books, no magazines, no video games, no music in English but for that which I encounter by chance in passing being played by someone else.

This gives me a little under two weeks to gather as much as possible.

In English, I generally read between twenty and sixty books a month. A really hungry month can see me reading a hundred and fifty books. I read very swiftly and have just been accustomed from very early teenhood to constantly taking in many new stories and pieces of information in any given week. I'm a bit worried that devoting myself to a language I still very much struggle in will leave me frustrated or unsatisfied, but I'm willing to chance it because at this point I'm just moving too slowly.

So--suggestions?
Places I can find cheap manga? I prefer what I can hold in my hand and take on the bus to what I must read on the computer.
Musical groups I should listen to? I like Akino Arai, MUCC, Spitz, stuff like that.
Games I can play? These would have to be on DS, as I doubt my Gamecube or PS2(unmodded) are any good for non-US games.
Books and stories in simple-enough language (I don't mind turning to my kanji dictionary ten times a page, but thirty times a page is pushing it)?
Dramas I can download, movies I must see, etcetera? I've not actually seen that much in terms of Japanese television dramas--Hana Yori Dango, most of Hana Kimi, and Mei-Chan no Shitsuji are the extent of my experience.
(I'll admit it; I loved Mei-chan no Shitsuji. Embarrassing, yes, but ooh, so much fun.)

Many thanks in advance for anything you can suggest!

You guys kick so much ass!
Sorry it took me a couple of days to reply; I've been in the process of moving and don't have internet at the new place yet. But ooh, I have such a list of things to watch and read and listen to now! *thrilled*
