First, I don't see why you'd want slower flow in the rad, because more flow is better. On the other hand, your overall flow rate would be lower, if everything was in the same loop.

I don't think you need 4" PVC: 1 1/2" should be more than plenty. You can build a column of Y fittings, that should work very nicely. I'm going to refer you to this:

if you keep the flow speed under 5 fps, then you're OK.

If you really want to run the rad on its own pump, then the only thing you have to worry about, is making sure that the cooled fluid is distributed evenly. There are many ways to do this.
