Trying to rebuild credit with lots of anxiety

Hello everyone, I have some questions that I hope someone out there can answer.  I am in the process of fixing my credit score which is currently 598.  I have paid off 3 CA yesterday and became current on 2 student loans.  I do have a judgement against me from 2003.  Last month I was informed they are going to start garnishing my wages 10% biweekly.  My husband and I currently own our own home but the mortgage is in his name.  I want to be able to buy a home next year using my name and income only.  What are the chances of this happening now that I have this GD judgement on my credit? The judgement is for $1800 and they are taking around $400 per month out of my salary. 

 

Is there a way I can check my current FICO score for free at this time?

 

Any help you can give me would be greatly appreciated!! I am so anxious to start cleaning up my credit but sometimes I just want to give up.
