You'll get a CEL and a code but it's nothing to worry about. The CEL will go away after 4-5 engine starts if you plug the EGR back in. Many people have driven for years and thousands of miles with the EGR unplugged with no issues.

Is it better for the truck to run with it unplugged?

It's a step in the right direction. It will drastically reduce the amount of soot going back through the engine.

No. The EGR and DPF serve different purposes. I see the logic of your thinking but the DPF will be fine with the relatively small amount of soot not going through the EGR
