Sorry for the delay, the question got accidentally closed.
I do not have his full name. Is this a problem?
No, as long as you have a first and last name that will be sufficient for now.
Should I not cite him individually, without full name?
Just use his first and last name
Should I serve to registered agent?
If the company has a registered agent for service of process then that is who you serve when you sue the company.
Does my statement of claim look good?
We're not allowed to give you much information on that but I pointed out the things I saw above, which were really more issues as to form than substance. One other thing I cna point out is that many judges won't allow you to file for an amount that is less than you are owed just to fit within their jurisdiction. I don't know about your judge but if you have one like that and they see the line that says yo are owed more than you are suing for, the judge may tell you that you have to sue in another court. If it happens, it happens, but I just wanted to make you aware.
As a last point, you spent a lot of time speaking about the damages but not much about why he owes you the money. You want tant to go into that a little more.
