I think you've pretty much got what you need. If you're building your own SBR on a Form 1, thoroughly test the existing pistol/rifle to make sure it is 100% functional and reliable. Then follow the Form 1 guide thread (note that there are relevant updates later in the thread that aren't in the OP). Then wait for your stamp, don't build it until you have the approved form (via email) in hand and other applicable requirements (e.g. engraving) taken care of.
That said, I just wanted to comment...

What a sad state of affairs for gun owners that we've been treated so poorly, attacked, and generally fucked over that we have to feel like
anything - even a huge, expensive, pain in the ass process such as the whole NFA circus is - is "too easy" with respect to exercising our rights. It reminds me of an abused woman who worries whether or not she got the dishes clean enough to avoid another beating.
That sort of thing ticks me off and I hate the entire shit show of having to constantly worry whether or not some new law, rule, or enforcement opinion will come down the pipe and make it harder to do what we enjoy. What precious few, if any, other groups of citizens have to deal with the government band saw always being so close to their balls like this to enjoy the legal activities of their choice? Much less an activity that is explicitly protected by the constitution.
