I'd add that a couple of 400's this year will likely be better for new audaxers than getting the 600 in. This particularly applies if you do some of the ones that start at 10am onwards as you're guaranteed to get the experience of overnight riding. 400k doesn't quite lend itself to having a proper sleep stop so you get the catnapping thing in as well.
Training wise I'd advise on making sure that from now on, the day after you do a 200k, you make sure you get up and ride again in the morning. Good experience for getting the legs going again after a sleep and the legs tightening up. Aiming for an RRtY into 2015 will also do wonders for keeping your fitness up and making the qualifying a less daunting experience.
That's all pretty sound and reliable advice.
