I don't consider myself an expert but I do lawn care for a living now.

It is amazing how different things are depending on what part of the country or what zone you are in. I could tell you something that is true for west Texas that might not be true at all where you are so some internet info may be all wrong. It is a joy to talk to old timers who have good lawns as well as guys who have run nurserys for years and just pick their brain. They love to find people who listen more than they talk.

Some generalities...ideally you would want to apply a pre-emergent weed killer way earlier in the year. At this point you are just going to battle them all year.

When I see bare or brown spots on turf here it usually indicates grub worms.
I don't know if that is true in your area.
