Great job!

What is the r factor of the foam you used?

When you get ready to run the system, cut the glycol back to 30 %, you will still have adequate freeze protection and have a higher heat transfer efficiency.
Check out Munchkin boilers.
Taco makes a good circuit setter for the money.
Make sure your expansion tank is for glycol and not for potable water
