As Sting pointed out some subject matter books are a real good start point. I just have “Pumping Away” along with many links I gathered and reviewed before the start of my project and as you are wisely doing reaching out to the many subject matter experts at this forum.
I have a some pics of my install over at the Leisure Line Stove Company Forum http://nepacrossroads.com/about24010.html
I elected to layout and build up a pump board (Pri/Sec config.) so that I could do most of my copper soldering at the work bench. Even soldered up a port to pressurize the system with air to check for leaks…….a bit of over kill but this added a measure of confidence in my work before cutting the pump board into my system.
I went from zone valves to cir. pumps on my loops also used a Taco SR503 for pump control to help keep the wiring a bit more simplified for me.
As others mentioned I used my longest loop for my dump zone. I have the trip point set for 215F and it very seldom trips during the heating season. I feel I have the WL110 dialed in for my set up.
As mentioned with a low mass boiler more mass will help buffer WL110 boiler temp swings on calls for heat. You could add mass something like Rob mentioned in another post a "Boiler Buddy"down the road to your system.
If you are in a hurry look for an assist from a qualified family member, friend or contract out all or parts of the install if you can find a contractor that will work with you.
