since your not moving camp - i'd suggest a big tarp for added 'living space' and the added protection from weather in your stationary, long-term base camp.
you already have a bug net for your eno- so that's that.
get an underquilt. since its summer in ohio, you'd likely be good with one rated to 40*- and can vent if needed. i'd go full length, since weight isn't an issue, plus no fussing with a pad, set it once and you're good.
if you have money, buy a tq-- it makes it easier to 'get setup' and comfortable. or if you diy, cannibalize an sleeping bag. or... just use the bag you used last summer.
those, imho, are the big 4. if you get adventurous, add a "footline" for leg support when wanting to lounge while wearing cruddy boots.
have fun. i used to stomp around kirtland, my family still lives there. the eastside is lovely. have fun!
