If Nitroethane is condensed with Acetic Acid & HCl this would yield what? I know that a good starting product for the preparation of Hydroxylamine
is Nitromethane, but I don't know exactly if Nitroethane is used. Methylamine might be favored?

I'm pretty sure you'd still get hydroxylamine. I know for certain that methylamine would not be formed.

With the nitroalkane + HCl method you will always get hydroxylamine and the corresponding carboxylic acid.
Nitromethane and HCl yield hydroxylamine and formic acid
Nitroethane and HCl yield hydroxylamine and acetic acid
I don't think adding acetic acid to the mix is going to do anything. In fact, here is a patent that shows that you can do the same reaction and
substitute a carboxylic acid for the HCl: https://www.google.com/patents/US3380807

Definitely don't waste your nitroethane on this. It's getting harder and harder to find.
If you want methylamine, do reformation of sulfamic acid.
Chemplayer did a couple videos on this.

If you use Zn/HCl, Fe/HCl or Sn/HCl (or SnCl2/HCl) you will end up with methylamonium or ethylamonium hydrochloride starting from nitrometane or
nitroethane respectively.

Easiest way by far is aluminum reduction of nitromethane. If you're a fan of the classic Al/Hg reduction, where you add mercury salt to a stirring
flask of water with aluminum pieces in it, I've developed a variant of that preparation that uses gallium and indium salts, but for reducing
nitromethane, alloying them beforehand (96% Al, 3% Ga, 1% In) is definitely an easier way to go about it.
