Terry, sounds like a great setup! I can't speak to the number of beans consumed by the Aeropress, I only use one scoop of beans per cup.
I normally make mine as a concentrate and add water. Once I've pressed the coffee through the filter there's about half a mug of coffee. I add water to suit. This method allows me to make two cups at a time by doubling the beans and water. I press half into one mug, half into the other and add water to both.
I generally only buy central or south American beans. But not Costa Rican, which is not robust enough for me. Although I roast mine into second crack, my wife likes hers about like yours.
One of the beauties of home roasting is that you can have any coffee roasted anyway you want. With such small batches, it's simple to make batches for each of us. My wife is delighted, especially since she expects, and gets, coffee in bed every morning. (I have to do something to make myself indispensable!)
Here's a photo of my Porlex Mini hand grinder. Very small. I can grind beans for only one or two (max) cups at a time.
