Healthy soil and sustainable growing

Hi, I'm new.

Even though I got a nice shiny new rototiller for Christmas this year, 
I'm perfectly willing to use it for small fire breaks, ground leveling 
and softening in areas I have to move dirt rather than my garden...BUT 
how do you get your mineral soil amendments in the ground? Just scatter 
them on top and leave them rather than tilling them in?

I seriously need sulfur added to my garden beds. My soil pH is 
marginally too high and my water pH is higher, so the pH in the garden 
is only going to go up.  This is my first time working this soil, and it 
is a former (small) pasture, even so, I am not supposed to till to 
loosen the soil if I understand correctly? Just scatter sulfur on top 
now and let sit there, or is it ok to work stuff in with something 
smaller than a tiller into the first inch or two?

I don't have a lot of hay or stuff. Pretty much the acreage I have is a 
lot of weeds and some grass. I can get some mulch from the grass.  Can I 
use mulch mowed from grass on the side of the road or is that still 
considered a bad idea?(Was it ever a bad idea?) I had also been 
contemplating planting some perennial alfalfa for future use, but I 
wonder if that would be too hot for mulching with. Everyone says alfalfa 
can burn plants, but does it if it's only on top of the soil? If I 
shredded up newspaper to add to the grass is that a bad idea, or should 
I stick to that for marking my permanent walkways with?

I'd appreciate any input.

Thanks,
