I would first take care of the Judgment first and formost. It won't improve your score by paying it but you will get rid of it and any possible means that they can enforce to satisfy the judgment ( wage garnishment, bank account seizure, tax refund seizure, and even asset seizure) So that should be your first concern.
Once that is done than get started on getting your balances down on your credit cards, having your balance under 30% will go a long way in improving your score.
You are right about the student loans not helping yet because they are in deferment. As of right now I would keep it that way so you can concentrate on the judgment and the cc balances. Once your student loan is out of deferrment and you start paying on time that will also help your score. But as from experience, DO NOT DEFAULT. It is a killer. IMHO the only thing worse than a BK on your credit score is a defaulted student loan, it will nuke it. So financially as of this moment it is probably best that it is stll in deferment.
so I would do this in this order
1. Take care of the judgment, the longer you wait the more you open up the possiblity of some form of seizure of assets.
2. Pay down your CC balances as low as possible
3. When Student loan is out of deferment, pay on time and don't miss a payment.
