Got it. Suing him for interfering with the easement will give you more tools you need.
The injunction is something that happens after a trial and with that the sheriff can have his stuff towed, arrested, etc. as he violated an injunction (court order to not do something. ie don’t mess with the road.) Same with dec relief, it just spells out court order. And cops can act on that.
I’m guessing the quiet title business is a play to keep the court from modifying the easement and giving it back to jerk. I still don’t think this is probable or necessary and just runs the meter.
The court may just issue a summary judgement based on all of your evidence. What are the defenses that could be used by the jerk? Probably not many.

So back to your original question – how to instruct the atty.
1. Send cease and desist letter by atty I mentioned previously. Probably won’t do anything but it lets court know you have made every effort.
2. Sue for the interference of easement. I would include all other people who use that road.
3. Stay on sheriff for enforcement.
