Rye n clover. Pines may have low pH from the needles. I'd throw some lime in the pine area, and you have have a significant layer of thatch the seed cant easily get into without some sort of prep.
Far as disturbing, I'd spray it atleast initially, then weedwhack it down after throwing your seed. Driving a ATV around after throwing seed is a good option. Could take 3 tires and some rope or chain and make a tire drag. Nice plus is you can leave it there year after year.
