You should really experiment with the game options yourself. Different computers will handle lowering certain options differently. You should stick with 1080p, just lower other options like textures, shadows, Render distance. Render distance in particular can be lowered without any visual quality loss.
SMAA is just another type of AA similar to FXAA and TXAA. The difference is it doesn't blur the whole screen as FXAA and TXAA do. In otherwords, you get the performance boost without the negative side effect.

It'll work with most DirectX games.
Should I use different settings for when I am streaming compared to recording? And I'm asking all of this because I have one screen, meaning I cannot monitor my stream or recording in real time. I have to analyze it after the fact, unless someone from here is happy to watch my stream and help me out a little bit today at around 2pm est.
I'm not free until late, but can help any day. Anytime after 9 PM EST is good for me.
About your questions, streaming requires more resources than just recording so you'll be able to set things higher when you are just recording. It may or may not be worth your effort to do so though. If it were me, I would just set it to one thing and be done with it.
You should also check your CPU and GPU usage to see if they are hitting 100 %. If either is, your system is able to easily overclock. You are only getting a bit of stuttering during intense action so a very small overclock would work and wouldn't effect your system's stability.
