Sorry only seeing this now. Depending on the part of the country you are at right now its too late/not worth it to aerate and overseed. Overseeding imo is the main reason you would want to aerate anyways. Right now what you can do is buy some some pre emergent weed control. Basically its stuff you would put down now to prevent weeds from popping up in the spring. Another thing you can do now if you chose is to put down a winterize, but you want to wait a couple of weeks, basically a day or two right before whenever the first hard freeze happens in your area
HD actually has a sale going on on the big scotts bag of there winterizer on sale, this will get you some weed control as well as some fertilizer for next year , your safe putting this down now at the bag recommended rate

If you really want to give yourself a boost for the spring grab a bag of this
https://www.homedepot.com/p/Milorganite-32-lbs-Slow-Release-Nitrogen-Fertilizer-100539618/308888983 and like i said before wait til two days before your first hard freeze and put it down at the bag recommened rate
As far as bugs my recommendation especially if you have a older house or live in a area close to woods is to go ahead and higher a pest control company to come and spray once a month, if you want to do it yourself this ortho stuff is pretty good
