File the appeal REQUEST. "The determination dated mm/dd/yy is wrong. I want an appeal hearing scheduled," is sufficient to get you a hearing.
You don't need to, nor do you want to. As a fired employee, it's the EMPLOYER that better bring the evidence to the hearing. You'll get a chance to see the evidence. Since you say it doesn't exist, it won't be a problem at your hearing. What you don't want to do is tip off your employer what they need to do at the hearing so don't ask or question why there were no documents submitted to you.
You'll get access to a hearing file or packet. It will have really good stuff in there so you'll have a rough idea of what might happen at the hearing.
You say you were fired because of calling your coworkers names. They better be at your hearing to testify against you, or the person at your hearing saying you said it better have heard it with their own ears, or you can admit it and do your employer's job for them. Hearsay evidence can be and should be objected to at least once. 90% of the time the judge says, "hearsay evidence is allowed, and will be given it's proper weight," but the catch is if you don't object to it at the hearing, then you can't use it as a basis for your board of review appeal if necessary.
Up to you on the attorney. As to the documents, as a fired employee it's not your job to prove some alternate theory for your discharge. Unless you have a letter that says you were "laid off," then what's the point in substituting one bad story that might be difficult to correctly prove at a hearing with one that you're willing to prove with documentation that you seem to sort of agree with.

Remember that you don't have to prove that you didn't do what the employer said, the employer needs to prove by a preponderance of the evidence that you did. Sounds like you work for a small outfit, and the employer has a business to run. Chances are, he's not coming to the hearing nor can afford to pay the right people to come to the hearing. Things will be decidedly in your favor so long as you didn't make admissions that ruin it for you.
