-Why is the coolant routed up to the throttle body? AWS?
And while I'm at it, wasn't able to procure PFA tubing to replace the oil injection lines, will small-engine fuel line work?

The BAC (Idle control valve) it doesn't need coolant to work properly. It's only beneficial in cold climates. I don't use it on my own FC and it gets down to 8 degrees in TX a couple days a year.
The coolant to the throttle body is not the AWS its for the choke plates a helps warm the car up. You can remove that stuff too. But you will have to tap the holes left by removing the choke plate shaft with a 1/8" npt tap and put plugs in it. The thermowax valve thing on the side of the throttle body go away at the same time as well. The AWS is the wierd little valve near the IAT just under the edge of the upper mamnifold. Also near the PCV valve. AWS has the huge hoses on it. This could also be disabled but the valve must remain plugged in or the check engine light will turn on.
Somewhere online there's a parts list for the OMP lines you buy all the stuff at McMaster Carr and it cost like $50 for all of it. I don't have a list myself just search around you'll find it.
