Settings for remote speedlights at large events

I might suggest learning lighting. As example, you say you like the Stofen on the flash as that prevents "blow out". How and why does it do that? Why point the flash directly at any subject? Why not bounce it off a wall or ceiling? Would you want to use the Stofen or not use the Stofen when doing this? I am not saying you should or shouldn't point the flash at your subject/group, but you need to know why you are doing this. The reason you want to know why, the reason you want to learn lighting, is that every situation will be different. What works in one room may not work in another. Or what works for one shot, may not work as well for another. Not that you would need to change the lighting set up, but you would want to be aware of what works best for what you have set up. The defacto standard book would be "Light: the Science and Magic". KelyTraining has some lighting tutorials, although I don't know if I can recall any specific reception lighting tutorials. David Ziser has a book "Captured by the Light' that discusses wedding lighting in general from start to finish. And I am sure there are other resources out there. Another great option is to assist with someone who knows what they are doing and can explain why they are doing it that way... but that might be a hard if you are already shooting your own weddings, nobody wants to directly train their competition.
