The issue I have with going right at the frets is that you don't know what the problem is and you are only fixing the current issue and not resolving the underlying problem. If it is the truss rod needs adjusting because of seasonal changes, then leveling the frets is great for the next 6 months. But then when the weather swings again, you have new problems because you didn't fix the correct problem.
There are at least 7 steps to a proper setup, once you know the frets are level. Without the proper tools you can't perform a good setup, and from the OP it is clear he doesn't have those tools. Second you need to follow the steps in order. Jumping around the order throws off the balance of the setup and it won't get right. If he goes right at it to level the frets he has a 50/50 chance that he'll fix the problem. If he takes it to a tech, he'll know it is fixed right, and in the process have a better setup than he does now and a better playing guitar.
The original post says that "The only good tech is 2 hours away", not the only tech. So there are others around. For a full fret dressing or a refret, you only want to go to someone very good. For a general setup, anyone who calls themselves a guitar repairman or guitar tech had better be able to do a setup, since that is the most basic and common work. I am sure if you ask around to some other guitarist or at local stores, they can tell you who is nearby that can do a good setup.
