The NASA form should protect you from enforcement penalties (ie suspension) but will not prevent you from getting a violation on your record.
The good news is that it sounds like it would be very hard for the FAA to find out...there's no requirement to report this to them. Even if they did find out I doubt they would bother with it...worst case they would probably invite you to the FSDO for a lecture and then bury the whole thing.
Even if it did get on your record, it would not keep from getting hired as long as you were honest about it. Except at eagle...you will never, ever under any circumstances be employed by AE or AA with this history. They would far rather go bankrupt for lack of pilots than even think about hiring you (and they probably will go bankrupt).
But I would be honest about it, it will make a good harmless interview story. It's also possible that you employer will report the incident via PRIA, although if you have a good relationship with him you could ask if he will report it. He has to report what's in your record, but if he didn't put anything in your record to begin with...
