So, seems like everyone agrees I should "lime" first. Is that just one big application of the 400 lbs of lime and then wait to do anything else until....when? And, this lime that I found out I can buy from a co-op, do I need to worry about my dogs getting in this stuff on the ground? Could it hurt them by breathing it in? Should I "water in" lime? Or just spread the stuff and walk.....?

Yes -apply it all at once and ideally water it - you can do that over days. Agricultural limestone is not toxic to dogs etc but you probably don’t want them carrying into the house if they are also house dogs. Just make sure it’s ag limestone or dolomite you are buying - people at the co-op should be selling you the right product.

I don’t think you need to do anything until next spring, fertilization wise, unless you want to give the Bermudagrass another shot of high nitrogen this month, in which case do that, wait until Oct or so before you apply lime.

The purpose of the lime is to raise soil pH, so that nutrients, primarily phosphorus, is readily available to the turf grass. At low, acidic soil pH, much of the phosphorus is sequestered in very insoluble aluminum and iron mineral complexes and not readily available to the grass, liming functionally increases the availability of soil phosphorus.
