Not sure what you mean by entering the job right out of high school, what does that have to do with what Mr. K said?
The DEFENSE attorney (yes we do know which attorney you're talking about) is probably planning to closely inspect ("flyspeck") your written interactions with your former employer to determine if you've ever lied to your former employer.
The defense attorney wants to see all your previous financial records and your UI records to see what kind of compensation you might be asking for should the defense attorney try to settle.
This is pretty much exactly what Mr. K told you, hope you get it this time.
