My native Japanese professor friend has stressed over and over with me the importance of listening to as much Japanese as possible.
The most concentrated and powerful preparation for the JLPT for me has been to buy companion audio CDs that match the content of the textbooks I use. I listen to the CDs (and converted MP3s) over and over during the day, even when I am working on other things and cannot give them my full concentration. This has the advantage of specifically reinforcing listening ability with grammar and vocabulary that is pertinent to your studies.
I also use Japanese movies as a less stressful and more enjoyable way to work on my listening comprehension, but some movies are definitely better than others for listening practice. [Hint: Avoid Samurai movies and historical dramas if modern Japanese listening comprehension practice is your primary goal from watching Japanese movies.]
Maybe some others out here can recommend text books suitable for level 2 progression that also have companion audio available. I would be interested in those as well. I will only take level 3 this December, but I plan to start working on level 2 content well before the end of this year.
