I know this is an old thread, just wanted to say........
Good advice, Hinfrance.
Always be careful and patient, when you adjust the truss rod.
I recently set up a friends Gibson acoustic. It was quite old, so I treated it with strong but cautious hands anyway.
I ended up giving it more than 2 full turns on the truss rod! But, in increments of 1/4 turn, and waiting a couple days in between. Took forever, but, it is getting played with a smile everyday, now..... so the effort was worth it!
Generally speaking, if the neck is good (straight), then I'd aim for an almost flat fretboard, with just a slight raise at the nut end (so, very slightly concave).
As Hinfrance mentioned, set intonation and action first! The action will buzz and fart, at first, but when you set the truss rod, and get the neck right, it should all sound sweet, in the end.
