I thought I replied to this earlier, but I must have wandered off. In regard to your truss rod, you want the neck to be as perfectly flat as possible. Usually that means a slack truss rod, but in the case of some older instruments, you may have to make some adjustments with NO string tension on the neck. See, you want the fingerboard to be a flat plane and then make all the tops of the frets a flat plane as you level. And, if the fingerboard is not flat from end to end, you will be removing a lot of fret in some places and hardly any in others. You don't want to do that. So, sight down the fingerboard. If you look, you can tell if its flat or not. You can get one of those fancy Stew mac tools that checks for flatness, but a good eye will work too. Once the board is flat, just level until you begin to see that you are taking material from all the frets, then stop. String it up and check fretting on every note. If you find high spots, mark them and go back and get them level too. Then, you can do the crown and polish and be in good shape.
