Here's a post I made back in 2010 on the matter in regards to my ability - http://forum.koohii.com/thread-3666.html
TL-DR: Take one drama episode that you like (say episode 1 of Hana Yori Dango). Use subs2srs to put it into Anki (each card will be 1 image, 1 subtitle line and 1 audio clip from that subtitle line). Figure out the entire episode line by line so you know or understand what each word means and what the entire sentence means in context. Put whatever notes you used to help figure that out in the "notes" section of Anki.
While you're during this, as you finish ~5 minutes of audio, rewatch the episode to that point without subtitles and notice how much you do or do not understand. Keep doing this till you're done.
When you're done with that episode, rip the audio and put on your phone and listen to it constantly. Print out the subtitle file and read along if you want. Print out the Drama Note script for the episode if you can find it and read that as well. Keep doing doing as you move onto another episode (either same or different drama).
What happens is you created a one hour foreign language listening tool that's comprised of material you completely comprehend. This comprehensive audio is native speakers talking at a native speed about native subjects. It takes time for you to create it, but each hour you create is a tool that you can listen to for hours on end to build your listening skills.
