I used to listen to liveatc using the iphone app on the train just to train my ear to listening to what was going on and get some of the patter down. For example tracking an aircraft through its approach and following what calls are occuring and getting a mental picture of what is going on. Also sometimes hearing some different requests and responses from say ATC than you might get in your own flying.
You need to pick a location that is close to what you are training on though, for example Bankstown, but they tend to be erratic with activity depending on time of the day. Listening to a larger class C area is more active but the calls are obviously different.
I also found practising my own calls in the car helped get the sequences and content straight in my head. Might seem a little goofy but it helps you work it in your head while doing other tasks rather than trying to do it just reading off a bit of paper.
