The Fall feeding is most important. It is important to fertilize you Saint Augustine before it goes dormant; this means mid-October to early November. If you want to prevent weeds, the best time to do it would be before the temperature drops below 65 degrees; many weeds, such as Crabgrass, have seeds that are triggered by the colder temperatures.
I do not know exactly where you live in the South so I cannot specify anything more specific.
Chipmunks eat any grass.
Probably St Augustine of Hippo because it invades everywhere and chokes out anything in it's path.. Amen - lol

All grasses are monocots.
too many big words!
There is not really any weed control out there that will kill one type of grass and not the other. If you want to get rid of Bahia grass in St. Augustine, you best bet is to spray the areas of Bahia grass with Roundup (the ready to use kind with the blue sprayer). Avoid as much of the St. Augustine as you can as Roundup is non selective, and then in the bare areas left by the dead Bahia grass you can put new St. Augustine in 7 days later. If the bare areas left are not too large, you can fertilize the St. Augustine encouraging it to spread into the bare areas.
It can grow in the shade, but will not do well under large trees.

Saint Augustine grass and Bermuda grass can coexist but there will be issues. Saint Augustine grass needs less fertilizer and usually grows faster. So it could make mowing the grass a frequent chore.
Plants are a complex mixture of thousands of different chemicals and do not have a "chemical formula."
You are going to need to fertilize you lawn. If the fertilizing is not helping, you will want to put down new grass seed.
