If you have not been sentenced you may be able to. If you have been sentenced, then the closest thing would be to file a 440 motion to vacate but you would need grounds for doing so (such as ineffective assistance of counsel and/or new evidence), and these are hard to win when you plead guilty.
Fraud would fall under litigation. You can use the "Find a lawyer" feature to search for litigation attorneys on Avvo. Otherwise, post a more detailed question, and contact one of the attorneys from your state that answer.
Assault occurs when one person intends for another individual to believe he/she will be subjected to imminent “harmful or offensive” contact.
In contrast, battery involves physical contact. It occurs when one person intends to cause “offensive or harmful” contact to another and such contact actually does take place. Thus, it would be a battery.
I really hope this isn't an exam question...

In most cases a person can represent themselves. This is called pro se representation. In the sort of case you describe you can represent yourself pro se, though it is advisable to have a lawyer represent you .A lot of cases like this are done on a contingency fee basis where the lawyer gets a percentage of any judgment awarded in your favor and so I would suggest you try to see if a lawyer would take this case on contingency before representing yourself.

What this means is that once you've purchased goods from a licensed dealer, you can then turn around and re-sell them provided that you sell them without any material alterations.

Since you're in Somers, I assume you'll be filing in the Southern District? You're fortunate because the Southern District has a pro se office to help self-represented litigants (which I assume you are) and you can contact them with questions like these. Their contact information is available at: http://www.nysd.uscourts.gov/courtrules_prose.php?prose=contact
Incidentally you won't be allowed to file anything until they review it (assuming you are representing yourself), so asking them about...
You should not post any more information on a public forum especially with your own name and the name of the Plaintiff. I'm sure this situation is very stressful for you but with a good lawyer it can be successfully resolved though you may need to pay a bit of money to BMI.
