FTF...
Stevek--You don't say in what state you'd be doing the selling, however in all but the most restrictive locales (Chicago, California, New York City, and Illinois come to mind) FTF sales are completely unregulated.
The party hands you the cash, you hand them the firearm, you smile and part ways, and that's that. No Federal paperwork on a FTF sale. It has to be a resident of your state, though. And some states expect you to collect sales tax and hand it over to them, although AFAIK there's no effective method of enforcing that.
For your own peace of mind I suggest that a bill of sale be used, stating the buyer's and the seller's identity, naming the goods and the amount of $$. I include the document that I use; you make 2 copies, both parties sign both copies, and both parties are protected. The document never becomes public unless in the future some question is raised about the sale--which IMX rarely happens.

SELLER’S COPY
******** ******** ******** ********
(Buyer gets an identical copy) The above handily fits all on one letter-size page.
I don't sell to those below 18; I don't deal with obvious gang-bangers or such. If it smells like the goods might be stolen, or in some other sense "wrong," I just don't do business. Note that I don't include any identifier such as a drivers' license number. I feel that such would be intrusive--and, hey, I'm NOT the police, nor trying to do their job. So far, it has worked for me, and no prospective buyer nor seller has shied away from a sale because of my wanting to use this document.
Hope you can work it out.
