@Bobvance and @alan are geographically very close to you. I’m on the other end of the state, and I’m also a noob with tree fruits. @scottfsmith’s annual reports were very helpful for me when choosing apples. He had bad luck growing Cox’s Orange Pippen in Maryland. Here is his most recent apple report and here is a peach report from him.
For apples I went with GoldRush, Hoople’s Antique Gold (the pair is pretty redundant, both being Golden Delicious types), and Kidd’s Orange Red (a Cox child).
As for pears, I ordered Harrow Sweet based on this old post of Alan’s on Gardenweb. He also had a similar post about GoldRush apple, which I cannot find. He might be able to point you in the right direction as far as stonefruit cultivars go.
Have you ever had a really good blueberry, or just store bought? Connecticut’s the perfect zone for growing them.
