Welcome to Permies, Matthew!
What climate zone map have you been looking at? If you check
here, you'll see that zone 6 has retreated into Missouri and you are probably in zone 8. Given that this reference is 7 seven years old, you could even be smack in the middle of zone 8.
I would say heavily wooded is a plus. The soil is probably in a healthier state than an acreage that has had row crops and conventional agriculture going on. You can selectively cut trees that you don't want and replace them with species that you do want.
