Randonneuring frame help

Here's my preliminary design. Rider is 18 y.o. male, 5'10" 220 lbs of muscle. All of his personal fit dimensions are plugged in already. I'm looking to make a Randonneur/All-Road bike. I've got qualitative questions, like:

Is there enough Fr-Ctr distance, is the wheelbase long enough, is there enough fork rake, what is my trail?

And quantitative questions:

Where do I find the above-mentioned stats? Once I settle on a geometry, how can I calculate tube lengths, tube angles, miters, etc.

Thanks!
