I've been using pimsleur as well, was able to find a pdf transcript to use alongside, which i found helpful. Also, anki (SRS flashcard system) works really well. I found a language coach at italki.com that sends me lists of words in a word doc and spoken into mp3, which i convert into flashcard using this method: http://www.zhtoolkit.com/posts/2011/05/creating-audio-flashc... (a lot of work the first time, about 5 minutes for 30 words the times after that).
