Lots of people add some vinegar at the end of a hot-sauce operation to either lower the pH further, for shelf-stability, or because they like the flavor. But I think the only thing it's going to do up front is slightly retard the fermentation process, I think. The culture brought in with some live vinegar might help convert alcohol to vinegar in a fruity sauce.
The sediment is quite small and hard to filter -- it's just dead bacteria. A coffee filter will get it out, I think, but it would be a bother. There's no real reason to do that. Taste it and see if you object. It's like tasting silt -- not exactly good and maybe a little gross to think about, but not really off-putting.
I assume you're going to blend the chiles and garlic, only adding in enough of the brine as needed for the blender. So, you won't end up with much of the sediment anyway. Once your sauce is made, it will have vanished.
